volanoMark 12% regression with 2.6.25-rc6

volanoMark 12% regression with 2.6.25-rc6

[Zhang, Yanmin]

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?

could you try sched/latest please? You can pick it up via:

Yanmin, how do you use volanomark; I got it from:

  http://www.volano.com/benchmarks.html

and am using java-1.6.0-openjdk.x86_64
I installed it /dev/shm/vmark to avoid disk io ruining anying

But I'm getting very fluctuating results, from ~43000 msgs/s to 52000
msgs/s.

This makes it very hard to 'trust' this benchmark, let alone determine a
regression.

IT disables the git connections. I could use rsync, but it's slow to download from
China.

Could you send me a patch against 2.6.25-rc6? Or just send me the kernel/sched*.c?

could you paste the rc5 and rc6 result lines you get out of Volanomark?

VolanoMark performance improvements (was: Re: volanoMark 12% regression with 2.6.25-rc6)

[Ingo Molnar]

i just tried a handful of kernels with VolanoMark on an Intel quad-core 
testbox, using java-1.6.0-openjdk-1.6.0.0-0.4.b06.fc9.

The result: v2.6.25 is the fastest ever Linux kernel in VolanoMark 
testing, -rc7-to-be is ~41% faster than v2.6.24.2, and ~59% faster than 
v2.6.21, in this Java benchmark:

v2.6.25-rc7-to-be:

  Average throughput = 145613 messages per second
  Average throughput = 142569 messages per second
  Average throughput = 144963 messages per second
  Average throughput = 144998 messages per second
  Average throughput = 144213 messages per second
  Average throughput = 144491 messages per second

v2.6.24.2:

  Average throughput = 101351 messages per second
  Average throughput =  99247 messages per second
  Average throughput = 101155 messages per second
  Average throughput = 103905 messages per second
  Average throughput =  98345 messages per second
  Average throughput = 102775 messages per second

v2.6.21:

  Average throughput =  87630 messages per second
  Average throughput =  91366 messages per second
  Average throughput =  91317 messages per second
  Average throughput =  91317 messages per second
  Average throughput =  91359 messages per second
  Average throughput =  92116 messages per second

these numbers are totally reproducible when running them over a long 
time, i only included 6 runs for brevity. (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? If you still see a regression 
with an open Java package too then could you please send me the .config 
of your test-kernel? Thanks,

	Ingo

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 :-)

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.

I installed FC9-Alpha x86_64 os on my 8-core stoakley. Then, I noticed
that the default kernel is 2.6.24.2. Did you use the default fc9-alpha kernel
to test it? If yes, the kernel config has big impact.

I retested it with java-1.7.0.

[root@lkp-st02-fc9 linux-2.6.24]# java -version
java version "1.7.0"
IcedTea Runtime Environment (build 1.7.0-b24)
IcedTea 64-Bit Server VM (build 1.7.0-b24, mixed mode)

java parameters are:
-Xms1500m -Xmx1500m -Xincgc

Pls. see the results below.

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%.

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.
