Subject: [mm] 4df910620b: will-it-scale.per_process_ops 37.7% improvement
Greeting,
FYI, we noticed a 37.7% improvement of will-it-scale.per_process_ops due to commit:
commit: 4df910620bebb5cfe234af16ac8f6474b60215fd ("mm: memcg: relayout structure mem_cgroup to avoid cache interference")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: will-it-scale
on test machine: 144 threads Intel(R) Xeon(R) CPU E7-8890 v3 @ 2.50GHz with 512G memory
with following parameters:
nr_task: 50%
mode: process
test: page_fault2
cpufreq_governor: performance
ucode: 0x16
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:
