Comparing with 2.6.25-rc5, volanoMark has 12% regression with 2.6.25-rc6
on my 8-core stoakley.
Bisect tracked it down to:
e22ecef1d2658ba54ed7d3fdb5d60829fb434c23 is first bad commit
commit e22ecef1d2658ba54ed7d3fdb5d60829fb434c23
Author: Ingo Molnar <mingo@elte.hu>
Date: Fri Mar 14 22:16:08 2008 +0100
sched: fix fair sleepers
Fair sleepers need to scale their latency target down by runqueue
weight. Otherwise busy systems will gain ever larger sleep bonus.

In the patch, vruntime -= calc_delta_fair(sysctl_sched_latency, &cfs_rq->load).
Should we call __sched_period to get the first parameter of calc_delta_fair in case
there are more than 5 tasks in the runqueue?

Thanks, I reduced COUNT to 2500, otherwise it took ages on my slowly machine :-) Also, I don't have jrocket, so I stuck with openjdk as that is the official open source JRE (afaik). Using the below patch, I get: sched_features=319: Average throughput = 65984 messages per second Average throughput = 64568 messages per second Average throughput = 66059 messages per second sched_features=63: Average throughput = 52536 messages per second Average throughput = 53592 messages per second Average throughput = 51705 messages per second Which seems to suggest the current code does better for me. (fwiw this is with compat_yield=0) sched_features=319, sched_compat_yield=1: Average throughput = 47669 messages per second Average throughput = 47435 messages per second Average throughput = 47120 messages per second [ this is in stark contradiction to all these Java _needs_ compat_yield=1 stories I keep hearing.. ] This is on a single dual core opteron. So given these numbers, I'm inclined to say openjdk is a better behaving JRE than jrocket - but what do I know about these things :-) --- diff --git a/kernel/sched.c b/kernel/sched.c index cc47766..32363cc 100644 --- a/kernel/sched.c +++ b/kernel/sched.c @@ -714,6 +714,7 @@ enum { SCHED_FEAT_SYNC_WAKEUPS = 32, SCHED_FEAT_HRTICK = 64, SCHED_FEAT_DOUBLE_TICK = 128, + SCHED_FEAT_NORMALIZED_SLEEPER = 256, }; const_debug unsigned int sysctl_sched_features = @@ -724,7 +725,8 @@ const_debug unsigned int sysctl_sched_features = SCHED_FEAT_CACHE_HOT_BUDDY * 1 | SCHED_FEAT_SYNC_WAKEUPS * 1 | SCHED_FEAT_HRTICK * 0 | - SCHED_FEAT_DOUBLE_TICK * 0; + SCHED_FEAT_DOUBLE_TICK * 0 | + SCHED_FEAT_NORMALIZED_SLEEPER * 1; #define sched_feat(x) (sysctl_sched_features & SCHED_FEAT_##x) diff --git a/kernel/sched_fair.c b/kernel/sched_fair.c index fd01aab..3dc4a1a 100644 --- a/kernel/sched_fair.c +++ b/kernel/sched_fair.c @@ -501,8 +501,11 @@ place_entity(struct cfs_rq *cfs_rq, struct sched_entity *se, int initial) if (!initial) { /* sleeps upto a single latency don't count. */ if (sched_feat(NEW_FAIR_SLEEPERS)) { - vruntime -= calc_delta_fair(sysctl_sched_latency, - &cfs_rq->load); + if (sched_feat(NORMALIZED_SLEEPER)) + vruntime -= calc_delta_fair(sysctl_sched_latency, + &cfs_rq->load); + else + vruntime -= sysctl_sched_latency; } /* ensure we never gain time by being placed backwards. */ ^ permalink raw reply related [flat|nested] 12+ messages in thread

(A sidenote: the /proc/sys/kernel/compat_sched_yield switch of 0 or 1 has no effect on the .25-rc7 results, and it degraded the .24 results by about 35% so i kept it off there.) so i can see no 12% regression at all - but i have not tried all the zillions of older, binary-only Java distributions. So, to make the tests comparable, and to make some progress on this matter, could you please try java-1.6.0-openjdk - what kind of VolanoMark numbers do you get with it?

I used java-openjdk to test it with 2.6.25-rc5 by switching compat_sched_yield to 0/1. The result difference is about 30%. vmstat data when compat_sched_yield=0: procs -----------memory---------- ---swap-- -----io---- --system-- -----cpu------ r b swpd free buff cache si so bi bo in cs us sy id wa st 85 0 0 7584984 17128 79264 0 0 0 0 2 716494 37 60 3 0 0 94 0 0 7585168 17136 79256 0 0 0 64 7 723299 39 57 4 0 0 vmstat data when compat_sched_yield=0: procs -----------memory---------- ---swap-- -----io---- --system-- -----cpu------ r b swpd free buff cache si so bi bo in cs us sy id wa st 369 0 0 7580656 14364 75852 0 0 0 0 4 1013260 42 57 1 0 0 335 0 0 7580836 14364 75852 0 0 0 0 1 971081 41 58 1 0 0 414 0 0 7580932 14372 75852 0 0 0 64 7 955333 40 58 1 0 0 > > > > so i can see no 12% regression at all - but i have not tried all the > > zillions of older, binary-only Java distributions. > > > > So, to make the tests comparable, and to make some progress on this > > matter, could you please try java-1.6.0-openjdk - what kind of > > VolanoMark numbers do you get with it? > On my stoakley (2 quad-core processors, 2.66GHz), with jrockit-R27.3.1-jre1.5.0_11.x86_64: > v2.6.22:363062 > v2.6.24:390248 > v2.6.25-rc3:210276 > v2.6.25-rc4:379704 > v2.6.25-rc5:377723 > v2.6.25-rc6:322864 > The regression is reproducible. > > > On another tigerton(4 quad-core processors, 2.93GHz): > v2.6.25-rc5:577752 > v2.6.25-rc6:579936 > So there is no regression on tigerton. > > > > If you still see a regression > > with an open Java package too then could you please send me the .config > > of your test-kernel? > I will try openjdk. 2.6.24.2(default fc9_alpha kernel) 153833 Average throughput = 154748 messages per second Average throughput = 153833 messages per second Pure 2.6.24 327275 Average throughput = 329439 messages per second Average throughput = 327866 messages per second Average throughput = 324519 messages per second 2.6.25-rc5 321305 Average throughput = 327553 messages per second Average throughput = 317973 messages per second Average throughput = 318390 messages per second 321133 Average throughput = 324018 messages per second Average throughput = 318246 messages per second Average throughput = 321135 messages per second 2.6.25-rc6 293347 Average throughput = 301476 messages per second Average throughput = 289165 messages per second Average throughput = 289399 messages per second 289437 Average throughput = 294080 messages per second Average throughput = 285931 messages per second Average throughput = 288301 messages per second 2.6.25-rc6+revert_fix_fair_sleepers 288329 Average throughput = 293253 messages per second Average throughput = 285688 messages per second Average throughput = 286047 messages per second So comparing with 2.6.25-rc5, volanoMark has about 8~10% regression with 2.6.25-rc6. This time, reverting fix_fair_sleepers has no help. The result is not so good as jrockit's. Perhaps I don't know unofficial parameters of the open java. Sometimes a small parameter of java might cause a benchmark result big difference.
