Subject: [memcg] 059dd9003a: will-it-scale.per_process_ops -39.8% regression
Greeting,
FYI, we noticed a -39.8% regression of will-it-scale.per_process_ops due to commit:
commit: 059dd9003ad894ad7b2e47126cde89a3ec46e630 ("[patch 101/212] memcg: enable accounting for file lock caches")
url: https://github.com/0day-ci/linux/commits/Andrew-Morton/ia64-fix-typo-in-a-comment/20210903-065028
in testcase: will-it-scale
on test machine: 96 threads 2 sockets Ice Lake with 256G memory
with following parameters:
nr_task: 100%
mode: process
test: lock1
cpufreq_governor: performance
ucode: 0xb000280
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:
