Re: [Flexradio] CPU usage

[William H. Fite]

I had to reinstall windows the other day and, being in a hurry and not
watching what I was doing, I inadvertently installed the 32-bit version of
Win7.  Of my 16GB of RAM, it reported that it could utilize 2.93GB.  The
rest was just sitting there resting its electrons.

When I restored 64, the difference was immediately and gratifyingly obvious.

I have noticed MD exhibit that behavior without DDUtil, I have been trying
to reproduce it so I can get some info to Dave, K1FSY.

It seems to occur most often when using HRD SAT Tracker with xmit and rec
Doppler shifting going on.
I'm using VSPE with Win 7 64.

Re: [Flexradio] CPU speed stepping.

[Neal Campbell]

Sadly, on the processors with TurboBoost you have to enable Speedstep to get
the TurboBoost.

What I do is go to the Power Control Panel (assuming Win7 OS btw) and select
the High Performance profile. Then, in that profile go to 'change advanced
settings" and turn off Thermal Protection (I think thats what they call it,
its in the processor group of settings).

This will result in you achieving the Turbo boost performance without the OS
throttling back the cores.

What a crazy scheme (making you eat SpeedStep to get Turboboost).

[Flexradio] CPU Utilization Spike When FM Is Squelched

[Bill Roberts]

Just got around to installing PSDR 2.1.5 on my dual core, 2 GB RAM XP-SP3
system.  I have noticed the CPU utilization spike when RX is squelched,
although not to the same degree reported by others.  My typical CPU
utilization runs between 18 - 21% in all RX and TX modes including FM.  With
squelch open, CPU is roughly the same.  Squelching RX increases CPU to 39 -
41%, roughly double.  I experimented with "just barely squelched" and
squelch set to max and got the same results.

 

I will be interested to see how this is eventually resolved.

Re: [Flexradio] CPU load for Firewire

If you want to read about the Microsoft bug...

http://support.microsoft.com/kb/2450963/en-US

As you see, there is no real fix at this time.  The workaround is not very 
applicable for FLEX-x000 radios since 99% of the data stream is "meaningful" 
(isochronous data).

Hopefully the Firewire vendor will be able to achieve a more stable and 
standardized configuration.  The problem is that there is a serious bug in the 
Microsoft Win7 1394 Firewire bus driver.  Without going into much detail, it 
generates way too many ISR and DPC events when data is transferred on the 1394 
bus.  This generates a lot of interrupt overhead and extra CPU utilization for 
a data streaming process; neither are good.  The Firewire vendor has been 
working with Microsoft to get them to fix the bug, but so far getting Micro$oft 
to fix it has been challenging.

The interim workaround is to use the legacy (Vista) driver, which seems to help 
in most cases.

Re: [Flexradio] CPU performance

[Tim Ellison]

Jeff,

A chance of working?  Sure, but it might take a bit of work in the optimization 
department and even then, it might be lacking for everything you may want to do.

First off, Celeron processors are lacking in CPU L2 cache, which is very 
important for real-time audio processing applications for doing all of the 
floating point math that is required.  Also, USB/Firewire combo cards are not 
recommended (http://kc.flexradio.com/KnowledgebaseArticle50179.aspx).  

You will be able to get on the air with this configuration, but you may have to 
resort to slower sampling rates and larger buffers to get adequate performance. 
 Adding on HRD is also going to drag down system performance.  

My advice is to try it and see how it plays and go from there.  If you think 
you need a new PC, then definitely talk to Neal K3NC, as he is the guru of SDR 
PCs. http://www.flexradio.com/Products.aspx?topic=FlexReady_PC

I'm just about ready to go all in on a new Flex-5000.  Will probably be making

has a chance of getting on the air without going to the expense upgrading the 
aforementioned items right off the bat.  Here's what I have:

The answer I give is "try it." It costs you nothing but time and you may
find that it works satisfactorily. If you can put off the purchase of
another machine by even 6 months you are ahead of the game because, in 6
months there will be something that is better and cheaper than what you
could get today.

BTW, and against all conventional wisdom, I consider a lot of "essential"
software to also fall into the "bloatware" category. That includes firewall
and antivirus software. The solution to needing a firewall is to turn off
services that listen at UDP or TCP ports that you just don't use. If it is
not running it cannot be used to compromise your system. (And there is a LOT
running in your windows computer that you don't use and never will use.)
Likewise with Antivirus. For antivirus software to work it must, a) know
ahead of time what is a threat and, b) accept threatening things in so that
it can compare them to already-known threats. If you don't let anything in
except from specific sources (I only download software for my shack computer
from Flex, fldigi, and only three or four other places) then there is
nothing for your antivirus software to do.

That is how I run my station. You may consider me to be foolish and you may
well be right. But I haven't experienced an infection on any of my systems
in about 10 years now. (Last system that was infected was Linux system with
a compromised WU FTP client.)

YMMV.

[Flexradio] CPU performance

[Jeffrey Brown]

Greetings. I posted this to the Flex Forum the other day by haven't had but one 
response...so I though I'd try here as well.

I'm just about ready to go all in on a new Flex-5000.  Will probably 
be making the purchase around first of May.  This will be my first ever 
new hf radio, and hopefully one that will last a long time.  I'm pretty 
much sold on the fact that the hardware can be upgraded, firmware 
upgraded, and constant software improvement.  Anyway, I'd like to get my
 computer in shape before I make the purchase so hopefully, there'll be 
no surprises.  I've read up on the recommendations on cpu's, memory, and
 firewire cards.  From Flex's recommendations I'm a little lacking.  I'm
 wondering if my current setup even has a chance of getting on the air 
without going to the expense upgrading the aforementioned items right 
off the bat.  Here's what I have:

Intel Celeron dual core at 2.1ghz (overclocked) 1mb L2
4gb ddr2 800 ram (all the mobo will take)
dual dvi video card, 1gb ram
M-Aujdio Delta 2496 sound card (24-bit, 96khz)
Belkin usb/firewire card (ya, I know it's recommended against the combo, but 
it's free)
Win7 Ultimate x64

This is a dedicated shack computer and serves no other purpose so it's 
not full of random bloatware or anything.  I'd like to be able to run 
the newest PowerSDR and probably HRD/DM780 at the same time.  I'm not 
adverse to spending the money on a new cpu and a different firewire card
 in that's what's necessary for satisfactory operation.  I just know 
that in addition to the radio I'll also need to buy a decent mic and I 
don't know what else so I'd like to limit the initial cash impact if I

Re: [Flexradio] CPU performance spike

[Graham Haddock]

Mike:

XP does not do this.  Vista and Windows 7 do it.  MicroSoft knows about it,
and is working on it.

Move the USB buffer slider towards "Conservative." (Setup/General/Options)
to reduce the peaking.

Hint: You need to stop PowerSDR before the slider can be moved.
Then "Start"  PowerSDR again.

Re: [Flexradio] CPU % vs Window Size

[Neal Campbell]

Gud deal. It just sounded like your CPU was doing more heavy lifting than I
would have expected with that card.

I have had better luck with AMD/ATI chipsets on Windows, latency wise, than
nVidia. I know its the opposite in the linux world, I think AMD must like
all that free beer too much!

Re: [Flexradio] CPU % vs Window Size

OK . but strangely enough, bigger isn't factor . as I drag it incrementally
bigger by steps . the % changes in a not necessarily linear fashion . I can
get a much larger display to use less % than some smaller ones .

[Flexradio] CPU % vs Window Size

[Kevin Hobbs]

Hi

 

I have been experimenting with the PowerSDR window size. By changing the
vertical height of the window (to get more / less panadpter size), I see my
CPU % very by as much as 20% (from 5 - 25) with only minimal changes in the
size. Does anyone else see this?

Dave,

Subject: [Flexradio] CPU Usage & Interupts

Hi folks,

On my Athlon II 3GHz Win64 OS and using the onboard firewire (VIA) of my Mo Bo 
M489TD Pro / usb3 my cpu usage swings wildly from 3% to 30% running PwrSDR.  
The 4th core can get up of 99% of usage occasionally and when this occurs audio 
cracks and pops and CW keying timing falters a little.  No a great drama; 
happens rarely.  DPC's are low and tend to max at 120 uSEC which is alright.

 [Tim] Those are actually very good numbers for DPC latency,

Yet I've seen folks post similar specs and not get more than 9% CPU usage from 
similar systems.  So I need to polish by system up a bit.

Ive discovered through the task manager the process causing the high oscilation 
of CPU usage is a process called 'System Interupts.'   My 
question is... if disable the onboard firewire and install my PCI-E firewire 
card (TI FW 400 Agere Lucerne) would this improve my overall system usage.  I 
was under the impression that AMD interupts were managed by the CPU and not by 
an onboard controller so I am not sure.

[Tim] Maybe.  Try this test first.  Turn off the Panadapter display and see 
what happens to the CPU usage.  If it drops substantially, then you may need a 
BIOS and/or video driver update.  I have seen these types of issues with the 
video integrated into the motherboard before.

Tim has always recommended external cards I know but I was hoping on having 
keeping my PCI-E card in my old intel machine so I could simply transport the 
FLX-3K upstairs on bachelor nights :-)
[Tim] Yes, I am an advocate for bus connected Firewire cards that use the TI 
chipset.  I never have had a problem with them.

[Flexradio] CPU Usage & Interupts

[David Walker]

Hi folks,

On my Athlon II 3GHz Win64 OS and using the onboard firewire (VIA) of my 
Mo Bo M489TD Pro / usb3 my cpu usage swings wildly from 3% to 30% 
running PwrSDR.  The 4th core can get up of 99% of usage occasionally 
and when this occurs audio cracks and pops and CW keying timing falters 
a little.  No a great drama; happens rarely.  DPC's are low and tend to 
max at 120 uSEC which is alright.


Yet I've seen folks post similar specs and not get more than 9% CPU 
usage from similar systems.  So I need to polish by system up a bit.


Ive discovered through the task manager the process causing the high 
oscilation of CPU usage is a process called 'System Interupts.'   My 
question is... if disable the onboard firewire and install my PCI-E 
firewire card (TI FW 400 Agere Lucerne) would this improve my overall 
system usage.  I was under the impression that AMD interupts were 
managed by the CPU and not by an onboard controller so I am not sure.


Tim has always recommended external cards I know but I was hoping on 
having keeping my PCI-E card in my old intel machine so I could simply 
transport the FLX-3K upstairs on bachelor nights :-)


Dave.

[Flexradio] cpu % display gone after crash

[Robert Redmon]

My cpu usage display in Power SDR disappeared following a crash the 
other day, and I have not been able to restore it. I have reinstalled 
Net 1.1 and Net 3.5 and used  exctrist.exe in an attempt to re-enable 
the reporting function, but to no avail. Does anyone know what files are 
involved in PowerSDR's call for cpu usage? Any help would be 
appreciated. Understanding what happened would be priceless.

[Flexradio] CPU percent lost

[Dale Brown]

I too,have lost the CPU window at the bottom left of the PowerSDR 
Pretty Betty Blue2 screen.  I have not had the computer attached to 
the internet, so Microsoft updates is not the answer.  the last 
update was when I downloaded  .net 3.5 before loading Pretty Betty 
and 1.19.  Can anyone else with a FlexRadio 5000A and Pretty Betty 
skin see the CPU percent on their screen?  Dale KC2PZ

Re: [Flexradio] CPU %

"...computer OS is Windows 2000"

I believe that is the problem.  The fix in the KB is for XP, which is why you 
are having Windows Genuine Advantage issues.  I do not think Win2000 is part of

Tim,
Thank you for your help.  I should have looked in the KB before, but 
since I did´d remember of any previous occurrence in the reflector I 
just skipped it and asked directly.  Taking in account the work that 
means compiling and maintaining this resource and the amount of useful 
information that it provides, all flexers with a problem should search 
the KB before trying to find the solution by other means.  I took the 
wrong way in the style of "when everything else fails, read the manual".

The bad news is that first, I had problems with the "Windows Genuine 
Advantage" Microsoft´s policy when trying to download the tool mentioned 
in the KB (exctrlst.exe). I use a genuine legal copy of Windows 2k, but 
the MS  specified tools for  verifying it even does not run on my 
system, so being unable to verify that my system is "genuine" it  
negates access to the file.

I finally managed to obtain a copy and installed it. It says that the 
required dll (perfos.dll) was already active.  I tried to disable and 
then enable, but no change.
Probably my problem is not exactly the same addressed by the article, 
because even the text "CPU %" is missing (or overlaid by the Date/Time 
panel ) in the console, because in my console this panel is bottom 
aligned with the VFO one.
Testing with the ke5dto branch, whose console has the Date/Time panel 
positioned higher, I see the "CPU %" title  for about .5 seconds just 
after loading and then disappears.

My radio is a SDR-1000, and the computer OS is Windows 2000.

Maybe somebody has a clue about this.

[Flexradio] cpu load

[FireBrick]

this weekends SS contest really creates a cpu load on the computer I use for 
PWSDR and contesting/logging.

As I use CCU, the node software of VE7CC, I found that I could seriously 
lower my cpu use level by running the CCU software on the shack secondary 
computer.

And directing my logging/contest software to receive cluster spots from the 
secondary computer.

By placing the IP of the secondary computer as the source of cluster spots, 
I was able to drop cpu use by 10%.

[Flexradio] CPU Comments

[Eric Wachsmann]

>From Mr. Haighton who is having trouble getting this message through to the
reflector:

After reading the glowing  references to the CPU performance on SVN 1424 I
decided to try using an older Sony Laptop again – which I had purchased for
the SDR 1K some 3 years ago as it had a parallel port.
 I had stopped using this computer as it regularly showed 100% cpu usage
(using instead a dual core machine  which showed only 35/50% usage).
Now the 2.80 Ghz Pentium 4 with 1 GB memory XP home and SP2 is running at 18
to 47%  when set for best performance
WOW! what an improvement…….. TNX   Bob.

Re: [Flexradio] CPU resources

[Dudley Hurry]

That's right, there is not a Vista driver for the Flex USB to 
Parallel converter.   A standard parallel PCI card will work 
fine,  just be sure to notice the BASE address of the 
converter.   Some of them will use a 4 digit address like FF00, which 
you will have to highlight and manually type it in.   The 
Edirol  FA-66 is the only one of the sound options that has a true 
Vista driver.   I had the D44 card running intermittently under 
Vista,  but it was unstable.

I think its a problem with the USBIO driver...
Im just gonna grab a Parallel port card and cable...probably 30 bucks or 
so im guessing but Thanks for the reply :)

If you need a USB cable to serial converter for Vista try the KeySpan device
and download their Vista drivers off their web site. Have 3 of them they
work great. I am not sure that is what you were talking about, but if it is
what you are having problems with in the USB cable department this may help.

Re: [Flexradio] CPU Usage - need to reduce overhead?

[Charles Greene]

Carl,

Use the Tips for Optimizing Windows XP at the web 
site, Q10307.  My CPU went from 35% average to 
20% average on a 1.86 GHz P4 Sony laptop with 1.5 
GHz of RAM, running SVN 1408 with a FireBox after 
I optimized my XP Home.  The extra RAM helps 
too.  However,you probably have sufficient RAM if 
you optimize everything to get similar improvements.

Re: [Flexradio] CPU Usage - need to reduce overhead?

[Tim Ellison]

Any improvement that reduces the load on the CPU, such as a faster graphics 
engine with more memory can not hurt.  I can't guarantee you will see any 
improvement, but it has been reported that upgrading to new high performance 
graphics cards does lower CPU utilization.

Re: [Flexradio] CPU Usage - need to reduce overhead?

[Dale Boresz]

Hello Carl,

A separate video card should provide a significant performance increase. 
As a test, turn off the panadapter display by selecting "Off" from the 
"Display Mode" dropdown list beneath the panadapter display, and see how 
much your cpu usage drops. This will give you some idea of how much CPU 
is being used just for video display purposes. There are many other 
factors of course, but in general you'd like to offload as much of the 
video processing as possible from main CPU, and doing so should reduce 
your CPU usage considerably.

Re: [Flexradio] CPU load with Flex5000

[Tim Ellison]

A list of known compatible Firewire host controllers is in the KB
http://kb.flex-radio.com/article.aspx?id=10250

I have the FA-66 and the FLEX-5000 connected to the same Firewire host
controller (I am not "daisy chaining") them.

You can connect other devices through the FLEX-5000, but power is not
passed through, so the devices at the end of the chain need a separate
power supply.

Re: [Flexradio] CPU load with Flex5000

[Robert McGwier]

Neal:

10 percent LESS.  The Flex 5000 at 192000 is an intense consumer of 
firewire resources.  The CPU usage goes UP ten per cent and even this is 
variable depending on user hardware.

We do not have sufficient experience yet to say this card is great and 
this one is horrible.  We are using a new interface and even the 
manufacturer cannot yet provide a definitive list.


That said, several of the beta testers are running both the Flex 5000 
and the SDR-1000/FA-66 together.  I have not done this so I cannot 
answer the question daisy chained or not.  They may be running them in 
separate firewire ports.  I do know they are on the same computer.

Re: [Flexradio] CPU load with Flex5000

[Dale Boresz]

After consulting with other beta-testers, it looks like we're seeing an 
increase of about 10 to 20% CPU usage with the FLEX-5000 over the 
SDR-1000. This is probably going to be dependent upon the individual 
computer. My computer is a 3.0GHz Pentium P4 with 3GB RAM, and after 
examining it more closely, I'm seeing about a 10% increase.

[Flexradio] cpu slowly climbs in 1.8

[FireBrick]

If I have the Sub RX active.
at approximately 40%, PWSDR goes into meltdown.
FA-66
Control Panel settings  Buffer Size (min), WDM smaller, ASIO Smaller

Setup>Audio
Ediron FA-66 firewire
Buffer 2048, Sample Rate 19200

If in VAC the buffer is 512, Sample 12000

PSDR priority set to HIGH


I tried a lower FA-66 sample rate and that caused lots of noise and popping 
in audio.


I have PWSDR running (obviously)
DXBase 2007 (logging software)
VE7CCC (node software feeding cluster spots to DXBase 2007.
No firewall, no spyware, no email client, I am on a home network obviously.
(In fact, I'm writing this on the other shack machine as normal).

I'm pretty experienced in running as minimized as possible.
But this is a 3.2 dual core, 1gig of memory, and even though I've ran many 
processes with high priorties previously, (Even SETI distributed) never 
experienced this.

With one vfo enabled, cw, ssb, digital, it tends to run approx 18 to 20 CPU 
percent.
Enable sub RX and cpu climbs to 27 percent, no problems yet

Then slowly the cpu starts climbing like this
27
23

etc. etc. till at approx 45 percent it goes into noisy, crackling, popping 
and is unusable to copy a weak signal.
As the cpu use reaches critical mass, a increase in snapping/popping will 
warn of impending meltdown.

If I disable the sub rx, it immeadately returns to normal processing, at 
approx 18-20 percent cpu use.

I've watched Task Manager and seen nothing that precipitated a rise in cpu 
use.
running PWSDR alone, without DXBase or VE7CCC make no difference.
(I notice that Task Manager is lower by 2 percent than the CPU% indicated in 
PWSDR lower left corner.)

I'm a DXer.. (btw: Just got my BS7H qsls via LoTW a few moments ago), I MUST 
have a working sub receiver/split operation.

[Flexradio] cpu usage

[Jim McLester]

I am up and trotting with new machine (amd64x2 4600) and was getting audio 
dropouts.

FYI
The culprit turns out to be the hardware monitor for the chip/board temp - 
"easytune" ver et5.  The guilty process is "gui.exe". This comes with 
gigabyte boards.

I'll let the bios temp warning do the deeds!

[Flexradio] cpu

[Jim McLester]

thanks.

box is amd athlon 64 x2 4600 with 1g 800 mhz mem in 2 sticks.  Ints, 
can't tell yet, but it won't be doing much else when doing flex. ( I 
don't multi-task as well as I used to - leave it to the cpu!)

[Flexradio] cpu

[Jim McLester]

OK, built better pc.  What settings will get worst case cpu % with test 
drive ssb file ?  So far I haven't seen it over 10% and that only when 
changing something. Usually ride between 4 - 6 % on one core.

[Flexradio] CPU PERCENTAGE

[FireBrick]

Even though I'm running a Pent 4 3.2ghz with 1 gig of ram, I see a bit of 
CPU% jumps.

Dual monitors on a Nvidia dual card, running DXBase, on one monitor, 
WinWarbler and Cluster on the other.
Edirol sound system.

Right now with all that running, I'm seeing 28% to 35% cpu use.

I 'used to know' how to set a programs priotity, but can't find it now.
Would this give SDR 1.8 a bit more help?
I occasionally see/hear a blip or bit of latency.
Using the USB interface as no com/parallel ports.

Re: [Flexradio] CPU Percentage question

[kd5nwa]

And that 25% is average over the measuring period it could have gone 
way high for short periods, if its at the wrong time you drop audio. 
So to prevent that most people like to see those numbers as low as possible.

Re: [Flexradio] CPU Percentage question

Maybe Ross, over 70% will sure give lots of problems
If in the peaks you need temporary morethan 100%
some things are not done (in time).
Its realtime (Under windows)
 
If SDR1k uses only say 25% or so you can still do other things
on the same computer.

Re: [Flexradio] CPU Percentage question

[Edwin Marzan]

That may be true but if your old computer was using on 5% of something and 
your new and more powerful computer (faster processor, more RAM) uses 25% of 
something to do the same job that may indicate there is some type of 
optomization problem.

Re: [Flexradio] CPU Percentage question

[Tayloe Dan-P26412]

When my wife picked up a new laptop, I looked specifically for one that
had a separate graphics card.  It is relatively easy to identify these
laptops.  In most laps, the memory will not be 1 Gbyte, but something
smaller like 900 Mbyte.  This is because the video memory is shred with
the processor, slowing things down a lot, and the computer makers do not
count the memory dedicated to graphics.  Almost all the laptops (98%?)
were like this.

We ended up buying a Fijitsu that had a dedicated graphics subsystem
(6200? 6250? graphics processor) that was on clearance.  Much faster
than the Gateway that we had before.  This graphics subsystem is not the
latest and greatest, but much, much better than the run of the mill
shared CPU/video subsystems of the typical laptop.  

The very fastest graphics chips eat a lot of power.  The laptops with
the highest end graphics chips are very expensive $3K and really are not
designed to be run off of batteries except for a very short time.  Think
of them more as overpriced portable desktop units.  A system like the
one we got is a good compromise for a SDR system.

Jeff,

Normal.  As I mentioned before, I have a 1.8 GHz lap top with 12 MB 
RAM and it ran 20 to 30 % CPU and about once a minute, it would peak 
at 100% in which case the SDR display would freeze.  I upgraded to 
1.5G RAM and it runs 10 to 20 % and never peaks above about 50%.

[Flexradio] CPU %

[Dave & Nancy Ridge]

I, like Larry, built up a new computer just for the SDR. I used the video that 
was on the mother board. It went from 5-10% on my old machine to 20-30% on my 
new machine. I then put in a $90 video card (don't remember the name of the 
card) in the new computer and the CPU dropped to 5-10%.

I am not sure, but remember that laptops are using part of the "normal" memory

for video, and some of the processor as well. Maybe this was in the reflector 
already,

but than I missed it. Just mention it to be complete.

Jeff,

You have several things working against you on a laptop.

Disks are slower
Memory is slower
CPUs generally do not have as much cache memory
I/O busses are slower
Running more processes in background (things like battery power management)
Graphics are slower (have to conserve power)

Most laptops are burning 60 to 90 watts,  where desktops are over 200
to 400 watts (depending on graphics)

So maybe 60% on laptop is not too bad,  depending on laptop..

Re: [Flexradio] CPU Percentage question

[Larry W8ER]

Jeff,

I built up a small, but hopefully independent, computer to run the
Flex. My main machine that was doing the job before was a 2.8 G P4
with 512 MB and I also had CPU utilization figures in the single digits
(5-8%). I never had any performance issues with it. The new box is a
2.4 G P4 with 512 MB and upon firing it up I noticed CPU utilization if
26 to 32%. I increased memory to 1G, no help. Task manager said that I
had 700k +++ available. 512 MB seems plenty here. I swapped out the video
card from an old Matrox II with 4 meg of memory to another oldie ..
Nvidia GeForce2 mx400. It made a tremendous difference in CPU
utilization. My original 2.8 G machine is using the video built onto
the motherboard (Intel 865GBF).

It might be interesting to see what others are using for video cards
and maybe come up with some sort of guidelines on selecting one.

You run your machines harder than I do, then.

I'm still getting by just fine with my 2.4 GHz machine and 512 MB.

I run PowerSDR and there's less "glitching" than ever.  The main time it
hiccups now is when loading some (not all) web pages.  I presume this is
some sort of I/O bound problem, because it seems independent of CPU load,
at least in my unscientific observations of it it seems so.

Nothing else phases it and I can have all sorts of stuff running that I
suppose I shouldn't.

I suppose "real men" abandoned 512 MB a long time ago, but it is still
worth noting for the rest of us that it is actually possible to have a
very satisfactory SDR experience on 512 MB's worth of memory.

At least, I'm managing the trick and I'm not running the PowerSDR console
only, either.  Nor have I done all the special tuning to turn off unneeded
services, et. al.  I just run it.  The key seems to be the 2.4 GHz with
adequate cache.  At least, that's what my experience says.

Re: [Flexradio] CPU Percentage question

[Tim Ellison]

Laptops are basically designed to run for a long time on batteries.  To
do this there are a lot of "cut corners" to make battery life last
longer.

Most laptops are markedly slower that an equivalent desktop with the
same CPU, hard drive size and memory.

Re: [Flexradio] CPU Percentage question

[Ken Klein]

You're right, Bob.  I do have to do the full scan every so often, but that's
a small price to pay considering the drawbacks of the other virus packages
out there.  Using Avast, Spambayes, and Adaware (all free, btw) I've kept my
system running sweet and fast now for several years.  

(Oh yeah, I better not forget Registry First Aid, which isn't free, but
seems to be doing me a good job.)

Thanks,

Just be advised that free is not without cost.  You will have to do 
regular scans MANUALLY as they do not schedule them unless you pay (at

does work beautifully and they are as quick as any I have used on

Re: [Flexradio] CPU Percentage question

[Charles Greene]

Jeff,

512 MB RAM is not enough to keep from paging memory to the HD.  If 
you bring up the windows task manager and watch the memory parameters 
under Performance and try to correlate them with CPU %, it might give 
you a clue.  As to why other systems operate with 512 MB RAM, I don't 
have any idea.  My Lap Top doesn't page with 1.5 GB; 1 GB may be 
enough.  Whether this is the only problem, I doubt.

Re: [Flexradio] CPU Percentage question

[Jeff Anderson]

Hi Charles and everyone else who has replied.

I've run through a number of the recommendations, but so far, no joy.

 o No (or little) change if turn OFF the panadpter display.

 o No change if I change indexing per the method on N9VV's website (the
directions in the Flex KB didn't work for me).

 o No change if I disabled quite a few of the startup routines in MSCONFIG
(I didn't disable them all, as I was worried that the computer might come up
in an unusable mode.  Perhaps I should live dangerously.)

 o  No change if I increase the size of the virtual memory.

What's weird is that my other computer, a desk 3.2 GHz P4, runs fine.  Go
figure!

Thanks to all for the help, and best regards!  Will continue
experimenting...

I'm surprised the 2.8 GHz uses so much CPU time.  Have you optimized
XP per the guide?  I am running a 1.8 GHz Sony VAIO Lap Top with XP
Home and a PreSonus FireBox.  The the CPU runs 6 to 22 percent but

minute the CPU would hit 100 percent and pause briefly.  Now both the

percent may be a percent or two less, but that wasn't a problem
before.  If fact, the Sony runs faster than my last computer which
was a 2.1 GHz AMD desk top with 512 MB RAM.  I reduced the display
update rate to 12 FPS which is indistinguishable from 15 FPS, and I

I'm surprised the 2.8 GHz uses so much CPU time.  Have you optimized 
XP per the guide?  I am running a 1.8 GHz Sony VAIO Lap Top with XP 
Home and a PreSonus FireBox.  The the CPU runs 6 to 22 percent but 
usually stays between 11 and 19 percent, and it updates once every 
one to two seconds.  I recently upgraded to 1.5 GB RAM from 512 MB, 
primarily because my Grandson plays games on it and there were brief 
pauses in the action in which case he would get shot or his plane 
would crash.  Before the upgrade when running the SDR, about once per 
minute the CPU would hit 100 percent and pause briefly.  Now both the 
SDR and the games are happy, and there are no pauses.  The CPU 
percent may be a percent or two less, but that wasn't a problem 
before.  If fact, the Sony runs faster than my last computer which 
was a 2.1 GHz AMD desk top with 512 MB RAM.  I reduced the display 
update rate to 12 FPS which is indistinguishable from 15 FPS, and I 
optimized XP per the guide.  The Ram upgrade costs about $50 for an 
additional 512 MB and $115 for the additional 1 GB and is a 5 minute 
installation job.  Well worth it, as the only other thing you can do 
is upgrade the CPU which is a tough job in a Lap Top.

Re: [Flexradio] CPU Percentage question

[Tom Thompson]

Jeff,

I had that happen to me, also.  I could not find the culprit using the 
task manager, so I ran MSCONFIG under the run command and rebooted with 
a minimum configuration, i.e. most of the auto starting applications 
were not loaded.  The problem went away, so I again tried to find the 
culprit.  No luck!  Finally after running SpySweeper and Norton Virus 
remover, I was able to get the computer to boot up in the regular mode 
without the problem.  I guess it was a piece of hidden malware that did 
not show up on the task manager.

I hope this helps.

Re: [Flexradio] CPU Percentage question

[kd5nwa]

I had a similar problem, and what stopped it was the stopping of all 
unnecessary process that run in Windows. My PC started at 50% spiking 
to 75%, after the change it's now about 7% with no spikes. This is on 
a Dual processor Pentium III 1GHz PC. A Dell 220 Precision workstation.

I believe the spike is caused by Windows processes running in the 
background that cause your cache to be flushed.

Unfortunately you have to know a lot about windows to figure out how 
to optimize it, but there are sites that help you with the basic items.

Re: [Flexradio] CPU Percentage question

[Dudley Hurry]

Jeff,

Besides Intel's Speed-Step stuff,  be sure to turn off the 
wireless/bluetooth,  infrared port, along with the serial port (if it 
has one).   Biggest CPU burst program I found is Spyware detectors 
and anti-virus programs.  Turn those off.Also try turning off the 
panadapter, some of these video cards/chips (like Intel's integrated 
video )  will not run the graphics as effectively as a dedicated card 
graphics like those from ATI or NVidia.  Also check your MSCONFIG to 
see what programs are being installed at boot time.

Maybe some of this helps,

Thanks, Tim & Ken, for your replies.

Yesterday I tried turning off the panadapter (and also
reducing the display's FPS), and, surprisingly, that
didn't seem to change the cyclical nature of the mips
consumption.  (I'll have to experiement again this
evening and see if there's an overall change, though.)

Please forgive my dumb questions, but how does one:
 1) turn off indexing 
 2) ensure the cpu has some L2 cache  
 3) create a large swapfile

Thanks for your help!  I'll try to report back this
evening with results...

Re: [Flexradio] CPU Percentage question

[Eric Wachsmann]

A few more thoughts:

Does the cycle happen when PowerSDR is not running?  What about when running
with other audio applications using the FA-66?  Does it happen when you set
the display mode to Off?  

If the answer to all of these is no, then I'm not real sure where to point
you besides general optimizations already mentioned.  If it is a dual core
machine, you might try setting the CPU Affinity for the PowerSDR.exe process
to just one core (instead of both).  Beyond all of that, I think I would be
looking at a PCMCIA firewire card with which others have had success.
