Subject: [mm] f0a3a24b53: will-it-scale.per_process_ops 17.0% improvement
Greeting,
FYI, we noticed a 17.0% improvement of will-it-scale.per_process_ops due to commit:
commit: f0a3a24b532d9a7e56a33c5112b2a212ed6ec580 ("mm: memcg/slab: rework non-root kmem_cache lifecycle management")
https://kernel.googlesource.com/pub/scm/linux/kernel/git/torvalds/linux.git master
in testcase: will-it-scale
on test machine: 96 threads Intel(R) Xeon(R) CPU @ 2.30GHz with 128G memory
with following parameters:
nr_task: 50%
mode: process
test: open1
ucode: 0x400001c
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
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
bin/lkp install job.yaml # job file is attached in this email
bin/lkp run job.yaml
