[linus:master] [mm] 8d59d2214c: vm-scalability.throughput -36.6% regression

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

 




hi, Yosry Ahmed,

per your suggestion in
https://lore.kernel.org/all/CAJD7tkameJBrJQxRj+ibKL6-yd-i0wyoyv2cgZdh3ZepA1p7wA@xxxxxxxxxxxxxx/
"I think it would be useful to know if there are
regressions/improvements in other microbenchmarks, at least to
investigate whether they represent real regressions."

we still report below two regressions to you just FYI what we observed in our
microbenchmark tests.
(we still captured will-it-scale::fallocate regression but ignore here per
your commit message)


Hello,

kernel test robot noticed a -36.6% regression of vm-scalability.throughput on:


commit: 8d59d2214c2362e7a9d185d80b613e632581af7b ("mm: memcg: make stats flushing threshold per-memcg")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master

testcase: vm-scalability
test machine: 224 threads 4 sockets Intel(R) Xeon(R) Platinum 8380H CPU @ 2.90GHz (Cooper Lake) with 192G memory
parameters:

	runtime: 300s
	size: 1T
	test: lru-shm
	cpufreq_governor: performance

test-description: The motivation behind this suite is to exercise functions and regions of the mm/ of the Linux kernel which are of interest to us.
test-url: https://git.kernel.org/cgit/linux/kernel/git/wfg/vm-scalability.git/

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