Subject: [mm] 286e04b8ed: will-it-scale.per_thread_ops -8.0% regression
Greeting,
FYI, we noticed a -8.0% regression of will-it-scale.per_thread_ops due to commit:
commit: 286e04b8ed7a04279ae277f0f024430246ea5eec ("mm: memcg/slab: allocate obj_cgroups for non-root slab pages")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: will-it-scale
on test machine: 192 threads 4 sockets Intel(R) Xeon(R) Platinum 9242 CPU @ 2.30GHz with 192G memory
with following parameters:
nr_task: 16
mode: thread
test: brk1
cpufreq_governor: performance
ucode: 0x5003006
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:
