Re: performance degradation on -ac tree
There is a bit more clarity on the performance degradation issue now - In fact the degradation only appears when using iptables. It's just that sometime shortly after 2.4.2, the hit imposed by iptables got worse. For instance: netperf results without iptables with iptables - 2.4.2 400 MB/s 330 MB/s 2.4.3-ac10400 MB/s 250 MB/s BTW, the stock seawolf kernel gets the highest netperf results ever seen on this box, around 450 MB/sec, but with iptables or ipchains module loaded, it falls to about 270 MB/sec.

Re: performance degradation on -ac tree
There is a bit more clarity on the performance degradation issue now - In fact the degradation only appears when using iptables. It's just that sometime shortly after 2.4.2, the hit imposed by iptables got worse. For instance: netperf results without iptables with iptables - 2.4.2 400 MB/s 330 MB/s 2.4.3-ac10400 MB/s 250 MB/s BTW, the stock seawolf kernel gets the highest netperf results ever seen on this box, around 450 MB/sec, but with iptables or ipchains module loaded, it falls to about 270 MB/sec. Just a data point fyi - cu jjs - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
Re: performance degradation on -ac tree
Hi all, I've been lurking for some time now, unsure of whether I had some special issues in my own setup, but seeing these others come forward has emboldened me to speak out as well. I am running a RH 7.0 box with all updates and then some, and generally trying each new 2.4 pre patch or -ac variant, with the addition of Andrew Morton's low latency patches. I have been noticing a marked performance degradation with recent -ac kernels compared to Linus' versions. This is based mainly on 2 things, one precisely measurable, the other more objective, but tangible to me nonetheless. First, the quanitifiable test: I have noticed that with e.g. the 2.4.0-test kernels, and e.g. 2.4.2, netperf to localhost gets between 350-400 MB/s. With recent -ac kernels, e.g. 2.4.3-ac5, netperf to localhost gets more like 250 MB/sec. secondly, a subjective test: When giving it the quake 3 arena test, playing against internet opponents, e.g. 2.4.2 feels very responsive, and I seem to be able to run circles around opponents, dodge and turn very quickly. The same activity with recent -ac kernels feels like running through molasses, very sluggish, and it is I who am repeatedly outmaneuvered and embarrassed. It's quite awful.

Fun, but unrelated to networking... Fun, yes, and perhaps not directly related, however under high load, where the sheer numbet of interrupts per second begins to overwhelm the kernel, might it not be relevant? After all, the benchmarks do point to tangible improvements in the performance of network server apps. Or are you saying that the bottleneck is somewhere else completely, or that there wouldn't be a bottleneck in this case if certain kernel parameters were correctly set?

He probably removed the original kernel-devel package,

I'm glad you admit that Red Hat is every bit as sane as
debian, since the current shipping version does indeed
have the sort of /usr/include/linux hierarchy you have just

ibmtr.o does not like 2.4 [Was: IBM Model 350 does not like 2.4]
Hi, Just to follow up on my own post, the problem is way down in the network driver layer, specifically in the ibmtr driver - it seems to be happy with 2.2, and barfs with 2.4 - for now I replaced it with an IBM pci card (olympic driver) and 2.4 is now solid on the machine that had serious problems using the isa token ring card. I'l have a look at ibmtr if nobody beats me to it. jjs - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/

IBM Model 350 does not like 2.4
Hi All, I have 10 systems running 2.4 that are rock solid, but I have 1 system that has problems with 2.4.

A buglet with LVM-0.9.1
Hi, I discovered that lvm seems to have a problem with compaq raid controllers - the partitions don't have the normal names like /dev/sda1, but instead names like /dev/ida/c0d0p1 - lvm seems to works OK, but lvmdiskscan freaks... lvmdiskscan works normally on other systems, which have conventional disk controllers. This is OK - case: /tmp (tty/dev/pts/1): bash: 623 lvscan lvscan -- ACTIVE "/dev/lxlvm/lvm1" [3.12 GB] lvscan -- 1 logical volumes with 3.12 GB total in 1 volume group lvscan -- 1 active logical volumes This is OK too - case: /tmp (tty/dev/pts/1): bash: 622 df Filesystem 1k-blocks Used Available Use% Mounted on /dev/ida/c0d0p11007928220124736604 24% / /dev/ida/c0d0p82015904251196 1662304 14% /home /dev/ida/c0d0p71007928 240956488 1% /opt /dev/ida/c0d0p94031856 1660664 2166380 44% /usr /dev/ida/c0d0p32015920 61768 1851744 4% /var /dev/lxlvm/lvm13225352 1888308 1173204 62% /disks/backup But this is not in agreement: case: /tmp (tty/dev/pts/1): bash: 625 lvmdiskscan -v lvmdiskscan -- reading all disks / partitions (this may take a while...) lvmdiskscan -- filling directory cache... lvmdiskscan -- walking through all found disks / partitions lvmdiskscan -- /dev/ida/c0d0p1 [1000.06 MB] free whole disk lvmdiskscan -- no valid disks / partitions found lvmdiskscan -- please check your disk device special files!

Re: ps hang in 241-pre10
OK, here's the details you asked about: Soundblaster Awe 32 sound card Voodoo 3 pci video card Running Xfree86-4.0.0 (rpms from 3dfx.com) Playing unreal tournament, no special game options, just 800x600 graphics @ 16 bits. To recap, the symptoms (hung ps, etc) occurred on kernel 2.4.1-pre8 + low latency patches. (but I don't think the low latency patches had anything to do with it, based on the other reports) Hope this helps jjs David Ford wrote: > On 2.4.0-ac12, I played music for about 30 minutes without any problems.

Re: ps hang in 241-pre10
OK, It's official now, I didn't know if it was some weird hardware fluke or something, but one of the computers here exhibited the same problem - The system in question is a Pentium II 400, scsi only (aic7xxx), running 2.4.1-pre8 plus Andrew Morton's low latency patches. The user was playing unreal tournament at the time and reported that it "got weird all of a sudden". I logged in and tried to do a ps, but the ps froze after listing a few lines. weird, never saw that one before. The user rebooted, so there was further opportunity to investigate, but I thought I ought to mention it after seeing these reports! jjs Aaron Lehmann wrote: > On Sat, Jan 27, 2001 at 03:34:26PM +1100, John Sheahan wrote: > > Hi > > my box has been running 2.4.1-pre10 for three days. > > This morning I noticed odd behavioue - ps and top wouuld freeze > > with no output. > > I had the same problem with 2.4.1-pre10 and the zerocopy patchset. > I came home one day and xmms was frozen.

I have to agree - when I worked at the University of California, a number of us had SGI Indys in our offices. The desktop was lightning fast, and the graphics were awesome. This is no news to anybody, since SGI is known for graphics. The big surprise, however, came when we were trying to find the best nfs server platform, and benchmarked the SGI just for fun - as it turns out, a little Indy workstation blew away all other platforms, including some rather large expensive SPARC boxes, as an nfs server. So Irix clearly showed the best of both worlds - great latency and great throughput. I guess what I'm saying is, there are a lot of proven concepts in Irix, which work well in real life situations - don't throw out the baby with the bath water - jjs - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
