Re: ESXi client / NFS server performance
The NFS server (4.8 release) from which the exports are mounted is a
virtual guest on the ESXi 4.1 host.
Transfer rates to/from the virtual NFS server guest to another guest are
a little faster on average (which makes some modicum of sense in my
mind...) than from the NFS guest to a physically separate machine.
The VM guests are using em(4) if that's any help.

where my problem lies. Any pointers would be appreciated.
When I ran ESXi 3.5 I found i/o was painfully slow, even with local
disk
(and NFS performance with an OpenBSD server was appalling).
In general i/o performance in ESXi 4.1 seems a lot better, but I
haven't
tried it with OpenBSD as NFS server yet.
Thanks. I've performed some other testing and found other clients work
acceptably, so I'll assume it's an ESXi issue. Iperf tops out at 300
Mbps on my network, which sucks but it's better than the 50 Mbps NFS was
doing. I'll try upgrading to 4.1 this weekend and see if that helps.

snapshot upgrade won't skip fsck
I upgraded to a more current snapshot the other day and after fsck ran on the root partition, it asked if i wanted to fsck the other partitions. I typed "no", but it ran anyways, causing a failure and therefore aborting the install because some disks were missing. I have 2 usb hard drives in my /etc/fstab. I don't have these drives with me all the time, and had them unplugged during my upgrade (so i didn't inadvertently install to one of them). I tried to upgrade a couple times, but i have to comment out my usb drives before i can successfully run the upgrade. The upgrade asked me whether or not I wanted to fsck the other partitions, so i figure it should at least obey my answer.

OpenVPN with CARP
Hi all, I have a set of OpenBSD firewalls running CARP for failover and OpenVPN (in UDP mode) for remote access. The problem is that when I don't specify an address in the OpenVPN config file, return packets from the BSD boxes to remote clients are sent from the local interface address rather than the shared CARP address. It looks like packets generated from this box do the same. Is there a way to a) force the origination address for these packets to the CARP address (why wouldn't they do that anyway I wonder?) or b) NAT them in some way to make it work? Thanks for any help!
Re: iostat and more than one core
On 2010-11-17 18.23, Luis Useche wrote:
Doing a small disk benchmark in my laptop with dd, I found that dd and
iostats were reporting different numbers. To be precise, iostat was
returning half of the MB/sec than dd (24.5 vs 49 MB/sec).
Digging a bit on the iostat code, I realized that the "struct _disk" cpu
time was returning 200 timer ticks even though it was read every second. I
tested by booting my machine with bsd.sp (to use one core instead of two)
and now it was returning the right number.
I've noticed the same phenomenon with iostat but haven't had time to
investigate. So now I did some iostat runs on a few of my servers with
1, 2, 4 and 8 cores and can definitely verify your findings.
I also noted that the tty columns are affected by the same cpu scaling
problem, and your patch neatly fixes that as well.
It seems like the number of ticks are incrementing by a factor proportional
to the number of CPUs (I think this makes sense). This makes iostat to
report the wrong bandwidth disk utilization.
Here is a patch I implemented to fix the problem:

Yes, N900 is the only phone i'd consider atm. If i'd have to buy a linux phone (no alternative) it'd be a N900 and put Meego on it. Android is just too restrictive. The HTC 7 Pro hw looks nice, but without any docu or source ... Me personally will stick with my 6820 until i can test the first real Meego querty slider. (Now if there were 15k+ ppl preordering a phone with openbsd+pf there might be a chance to get something "good".)

W dniu 2010-11-17 22:11, Kenneth Gober pisze: this is very illuminating. it says that initially, tcp send/receive window is your bottleneck. when you increase them to 131072, the cpu becomes your bottleneck and remains that way no matter what else you tweak (idle drops to 0.0% and stays there). the next question is, of course, why is your cpu spending all its time in "system" and "interrupt"? is it doing unnecessary work, or is the work necessary and your cpu just isn't fast enough? I don't have ready answers to these questions. -ken Hello, I see, that while I am testing network speed by iperf, 100% CPU is being used, but is that normal for default install of OpenBSD 4.8 with default pf.conf?? I have second computer exactly like that one (IBM ThinkCentre A51P), on which i am running this tests but with P4 3Ghz CPU 2mb cache (not celeron 2.8) and the same is happening (100% CPU). LAN interface is Intel PRO/1000 PT Desktop Adapter (PCIe, model: EXPI9300PTBLK) and this is the only pcie adapter in computer (maybe broadcom integrated nic is also pcie but is not used) So the conclusion might be: - there is problem with my Intel NIC model/cheapset - there is problem with em driver - there is problem with my hardware (I need serwer motherboard with pcie and pci 64bit 66mhz) - I need faster CPU than P4 3GHz ?? best regards, RLW

Toshiba Satellite M30X and Realtek PCMCIA Based Card Issue.
Hello guys, im writing this to let you know about the problems that im facing with my toshiba satellite lapto and a pcmcia ethernet card based on the realtek chip 8139. Well i just want to build a new router box based on 4.8 (tried 4.7 too) so i just bought this card to use as the wan interface of the config. The problems came when i plug the card and this message appear: pcic_chip_socket_enable: status c pcic_wait_ready: ready never happened, status = 0c com3 at pcmcia0 funtion 0: can't allocate i/o space So when doing ifconfig i can't see the other if, i tried on freebsd and the nic appears as rl1 since the onboard nic its also a realtek 8139 based (rl0) what can be causing this? Thanks in advance.

Even if you get the file it wont "fix" what your hoping for. If anything I think the newer firmwares have higher fan rpm settings... Basically you looking at 2 realistic settings with this system. Really loud while the OS is running and insanely loud when its powering up/down under only the SP/BIOS control. That's just the way they are.
Number of static IP addresses needed for CARP
Hi all, I know this is a dumb-ass question but I've read the FM (including the new Book of PF 2) and there is a basic something I still don't understand about CARP. Right now I have a small network with 1 static IP and 1 firewall. I have a cat5 cable running directly from the cable modem to the $ext_if of the firewall. I want to replace my 1 firewall with a pair of new-to-me identical 1U servers with 4 em interfaces I understand that I'll need to drop a small switch between the cable modem and the redundant firewalls but what I don't understand clearly is how many real, external static IPs I'm going to need. Page 120 of the Book of PF 2 has a diagram that makes me think I'll need 3--carp0 on each firewall gets the IP I have now, and the $ext_if on each firewall gets another static IP each. Is that correct? Obviously I don't want to buy a couple more static IPs if I don't need them. Thanks in advance! Jeff Ross

iostat and more than one core
Hi Guys,
Doing a small disk benchmark in my laptop with dd, I found that dd and
iostats were reporting different numbers. To be precise, iostat was
returning half of the MB/sec than dd (24.5 vs 49 MB/sec).
Digging a bit on the iostat code, I realized that the "struct _disk" cpu
time was returning 200 timer ticks even though it was read every second. I
tested by booting my machine with bsd.sp (to use one core instead of two)
and now it was returning the right number.
It seems like the number of ticks are incrementing by a factor proportional
to the number of CPUs (I think this makes sense). This makes iostat to
report the wrong bandwidth disk utilization.
Here is a patch I implemented to fix the problem:

The choice was: Sun V20z. And Now?
Hi all, I've asked sometime ago about an "Architeture Choose" Ok, I've choose the Sun Fire V20z (2xAMD Opteron). As someone said, the fans are really loud... I've seen some articles about upgrading the BIOS can reduce the fans... BUT, when trying to download the latest firmware upgrade from Sun's website, no success. Anyone have this files? Thanks!

Thanks. I've performed some other testing and found other clients work acceptably, so I'll assume it's an ESXi issue. Iperf tops out at 300 Mbps on my network, which sucks but it's better than the 50 Mbps NFS was doing. I'll try upgrading to 4.1 this weekend and see if that helps. -Steve S.

This is a known issue with the 82578DC (82578DM doesn't show it). It is likely something along the lines of missing workarounds for particular revisions of the phy.

Has anyone higher speeds working with this PHY? if you have another machine with a gigabit port, just plug it straight in and see what happens: use a regular (not crossover) cable and make sure both machines are set to autoselect.

If I am reading it wright, no packets are droped.
Changing values like:
kern.somaxconn
net.inet.ip.maxqueue
net.bpf.bufsize
net.bpf.maxbufsize
net.inet.ipcomp.enable
net.inet.tcp.ackonpush
net.inet.tcp.ecn
does not help either. It only has some influence on network speed with
PF disabled. With PF enabled speed is alwasy around 350mbit/s :((
So any new ideas about debuging the problem or possible solution?

An OpenBSD smartphone
My twelve years old cell phone needs to get replaced, most probably with one of these newer smartphones. Beside other things, I want it to be as "open" as possible: a freely-available OS, a class-compliant USB storage, a documented wifi hardware, etc. So, in this regard: has someone managed to install obsd on some of these newer phones? I understand that most of these have an OS that is basically a modified linux; does anyone know about a varinat that would have an OS based on BSD? Thanks Jan
