Subject: [sched/fair] 0b0695f2b3:
phoronix-test-suite.compress-gzip.0.seconds 19.8% regression
Hi Vincent Guittot,
Below report FYI.
Last year, we actually reported an improvement "[sched/fair] 0b0695f2b3:
vm-scalability.median 3.1% improvement" on link [1].
but now we found the regression on pts.compress-gzip.
This seems align with what showed in "[v4,00/10] sched/fair: rework the CFS
load balance" (link [2]), where showed the reworked load balance could have
both positive and negative effect for different test suites.
And also from link [3], the patch set risks regressions.
We also confirmed this regression on another platform
(Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz with 8G memory),
below is the data (lower is better).
v5.4 4.1
fcf0553db6f4c79387864f6e4ab4a891601f395e 4.01
0b0695f2b34a4afa3f6e9aa1ff0e5336d8dad912 4.89
v5.5 5.18
v5.6 4.62
v5.7-rc2 4.53
v5.7-rc3 4.59
It seems there are some recovery on latest kernels, but not fully back.
We were just wondering whether you could share some lights the further works
on the load balance after patch set [2] which could cause the performance
change?
And whether you have plan to refine the load balance algorithm further?
thanks

Below is the detail regression report FYI.
Greeting,
FYI, we noticed a 19.8% regression of phoronix-test-suite.compress-gzip.0.seconds due to commit:
commit: 0b0695f2b34a4afa3f6e9aa1ff0e5336d8dad912 ("sched/fair: Rework load_balance()")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
