Subject: [memcg] 0f12156dff: will-it-scale.per_process_ops -33.6% regression
Greeting,
FYI, we noticed a -33.6% regression of will-it-scale.per_process_ops due to commit:
commit: 0f12156dff2862ac54235fc72703f18770769042 ("memcg: enable accounting for file lock caches")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: will-it-scale
on test machine: 104 threads 2 sockets Skylake with 192G memory
with following parameters:
nr_task: 50%
mode: process
test: lock1
cpufreq_governor: performance
ucode: 0x2006a0a
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 | will-it-scale: will-it-scale.per_process_ops -40.9% regression |
| test machine | 128 threads 2 sockets Intel(R) Xeon(R) Gold 6338 CPU @ 2.00GHz with 256G memory |
| test parameters | cpufreq_governor=performance |
| | mode=process |
| | nr_task=50% |
| | test=lock1 |
| | ucode=0xd000280 |
+------------------+---------------------------------------------------------------------------------+
If you fix the issue, kindly add following tag
