Pekka Enberg	Re: File corruption when using kernels 2.6.18+ Hi Neil, I don't but you can try to isolate the changeset introducing the corruption with git-bisect: http://kernel.org/pub/software/scm/git/docs/v1.3.3/howto/isolate-bugs-with-bisect.txt So, in your case, you do: <clone Linux mainline git repository> # git bisect start # git bisect bad v2.6.18 # git bisect good v2.6.17 then <recompile and test> <git bisect [good\|bad] depending on results> <repeat until you've narrowed down the changeset> Also, please rem...

Denys	2.6.21 -> 2.6.22 & 2.6.23-rc8 performance regression P.S. It seems SLAB/SLUB doesn't make much difference, just seems SLUB use a bit more some resources. Still problem appearing with softirqd/0 or softirqd/1 taking a lot CPU (while on 2.6.21 it never came up of the "top"), and doesn't matter - if NAPI on e1000 disabled or enabled. Additionally disabling all disk operations doesn't make any difference. defaulthost ~ #mpstat 1 Linux 2.6.23-rc8-build-0017 (defaulthost) 09/30/07 21:20:29 CPU %user %nice %sys %iowait %irq %sof...

Denys	2.6.21 -> 2.6.22 & 2.6.23-rc8 performance regression I've moved recently one of my proxies(squid and some compressing application) from 2.6.21 to 2.6.22, and notice huge performance drop. I think this is important, cause it can cause serious regression on some other workloads like busy web-servers and etc. After some analysis of different options i can bring more exact numbers: 2.6.21 able to process 500-550 requests/second and 15-20 Mbit/s of traffic, and working great without any slowdown or instability. 2.6.22 able to process only 250-300 ...

Eric Dumazet	Re: 2.6.21 -> 2.6.22 & 2.6.23-rc8 performance regression Could you try with SLUB but disabling CONFIG_SLUB_DEBUG ? -	Sep 30, 1:48 pm 2007
Nick Piggin	Re: 2.6.21 -> 2.6.22 & 2.6.23-rc8 performance regression Hi Denys, thanks for reporting (btw. please reply-to-all when replying on lkml). You say that SLAB is better than SLUB on an otherwise identical kernel, but I didn't see if you quantified the actual numbers? It sounds like there is still a regression with SLAB? -	Sep 30, 12:25 am 2007
Denys	Re: 2.6.21 -> 2.6.22 & 2.6.23-rc8 performance regression Hi I can confirm, that reversing this patch on 2.6.23-rc8 fixes the problem. Checked on 3 different servers. softirq not jumping anymore on top of "top" and mpstat also looks stable, reasonable and nice. pi linux-git # git bisect bad Bisecting: 0 revisions left to test after this [f85958151900f9d30fa5ff941b0ce71eaa45a7de] [NET]: random functions can use nsec resolution instead of usec -- Denys Fedoryshchenko Technical Manager Virtual ISP S.A.L. -	Sep 30, 7:24 pm 2007
