Greeting,
FYI, we noticed a 9.1% improvement of will-it-scale.per_process_ops due to commit:
commit: 60f97516388a0fc63bcaf31a1cb81d22d4b765b4 ("mm/page_alloc.c: Set ppc->high
fraction default to 512")
https://git.kernel.org/cgit/linux/kernel/git/saeed/linux.git net-next-mlx4
in testcase: will-it-scale
on test machine: 192 threads Skylake-SP with 256G memory
with following parameters:
nr_task: 100%
mode: process
test: page_fault2
cpufreq_governor: performance
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:
