FYI, we noticed hackbench.throughput -32.9% regression due to commit:
commit 53d3bc773eaa7ab1cf63585e76af7ee869d5e709 ("Revert "sched/fair: Fix
fairness issue on migration"")
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
in testcase: hackbench
on test machine: ivb42: 48 threads Ivytown Ivy Bridge-EP with 64G memory
with following parameters:
cpufreq_governor=performance/ipc=socket/mode=threads/nr_threads=50%
In addition to that, the commit also has significant impact on the following
tests:
unixbench: unixbench.score 25.9% improvement on test machine -
ivb42: 48 threads Ivytown Ivy Bridge-EP with 64G memory
with test parameters: cpufreq_governor=performance/nr_task=100%/test=context1
hackbench: hackbench.throughput -15.6% regression on test machine -
lkp-hsw-ep4: 72 threads Haswell-EP with 128G memory
with test parameters:
cpufreq_governor=performance/ipc=pipe/iterations=12/mode=process/nr_threads=50%
Details are as below:
