Hello,
kernel test robot noticed a -92.6% regression of stress-ng.epoll.ops_per_sec on:
commit: dcf70df2048d27c5d186f013f101a4aefd63aa41 ("af_unix: Fix up unix_edge.successor for embryo socket.")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
testcase: stress-ng
test machine: 64 threads 2 sockets Intel(R) Xeon(R) Gold 6346 CPU @ 3.10GHz (Ice Lake) with 256G memory
parameters:
nr_threads: 100%
testtime: 60s
test: epoll
cpufreq_governor: performance
If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags
| Reported-by: kernel test robot <oliver.sang@xxxxxxxxx>
| Closes: https://lore.kernel.org/oe-lkp/202404101427.92a08551-oliver.sang@xxxxxxxxx
we also noticed the data become less stable on this commit:
"stress-ng.epoll.ops_per_sec": [
47530.93,
40960.07,
332631.31,

37547.67,
40540.35,
42700.75,
298256.41,
50348.57
],
as a contrast, pretty stable on parent:
"stress-ng.epoll.ops_per_sec": [
