Subject: [sched/fair] 070f5e860e: reaim.jobs_per_min -10.5% regression
Greeting,
FYI, we noticed a -10.5% regression of reaim.jobs_per_min due to commit:
commit: 070f5e860ee2bf588c99ef7b4c202451faa48236 ("sched/fair: Take into account runnable_avg to classify group")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
in testcase: reaim
on test machine: 4 threads Intel(R) Core(TM) i3-3220 CPU @ 3.30GHz with 4G memory
with following parameters:
runtime: 300s
nr_task: 100%
test: five_sec
cpufreq_governor: performance
ucode: 0x21
test-description: REAIM is an updated and improved version of AIM 7 benchmark.
test-url: https://sourceforge.net/projects/re-aim-7/
If you fix the issue, kindly add following tag
Reported-by: kernel test robot <rong.a.chen@...el.com>
