Subject: [mm, memcg] 1e577f970f: will-it-scale.per_process_ops -7.2%
regression
Greeting,
FYI, we noticed a -7.2% regression of will-it-scale.per_process_ops due to commit:
commit: 1e577f970f66a53d429cbee37b36177c9712f488 ("mm, memcg: introduce memory.events.local")
https://kernel.googlesource.com/pub/scm/linux/kernel/git/torvalds/linux.git master
in testcase: will-it-scale
on test machine: 96 threads Intel(R) Xeon(R) CPU @ 2.30GHz with 128G memory
with following parameters:
nr_task: 50%
mode: process
test: page_fault2
ucode: 0x400001c
cpufreq_governor: performance
test-description: Will It Scale takes a testcase and runs it from 1 through to n parallel copies to see if the testcase will scale. It builds both a process and threads based test in order to see any differences between the two.
test-url: https://github.com/antonblanchard/will-it-scale
In addition to that, the commit also has significant impact on the following tests:
+------------------+------------------------------------------------------------------------+
| testcase: change | vm-scalability: vm-scalability.median -13.0% regression |
| test machine | 160 threads Intel(R) Xeon(R) CPU E7-8890 v4 @ 2.20GHz with 256G memory |
| test parameters | cpufreq_governor=performance |
| | runtime=300s |
| | size=1T |
| | test=lru-shm |
| | ucode=0xb000036 |
+------------------+------------------------------------------------------------------------+
