[linus:master] [memcg] 70a64b7919: stress-ng.shm.ops_per_sec -8.5% regression

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



hi, Shakeel,

besided what we reported will-it-scale regression in
https://lore.kernel.org/all/202405171353.b56b845-oliver.sang@xxxxxxxxx/

after this commit is merged into mainline, we noticed stress-ng regression.
so report again FYI. (still including will-it-scale results)



Hello,

kernel test robot noticed a -8.5% regression of stress-ng.shm.ops_per_sec on:


commit: 70a64b7919cbd6c12306051ff2825839a9d65605 ("memcg: dynamically allocate lruvec_stats")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.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: shm
	cpufreq_governor: performance


In addition to that, the commit also has significant impact on the following tests:
