Subject: [LKP] [sched/fair] 2c83362734: pft.faults_per_sec_per_cpu -41.4%
regression
Greeting,
FYI, we noticed a -41.4% regression of pft.faults_per_sec_per_cpu due to commit:
commit: 2c83362734dad8e48ccc0710b5cd2436a0323893 ("sched/fair: Consider SD_NUMA when selecting the most idle group to schedule on")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: pft
on test machine: 88 threads Intel(R) Xeon(R) CPU E5-2699 v4 @ 2.20GHz with 64G memory
with following parameters:
runtime: 300s
nr_task: 50%
cpufreq_governor: performance
ucode: 0xb00002e
test-description: Pft is the page fault test micro benchmark.
test-url: https://github.com/gormanm/pft
In addition to that, the commit also has significant impact on the following tests:
