Subject: [mm] 802f1d522d: stress-ng.memfd.ops_per_sec 8.7% improvement
Greeting,
FYI, we noticed a 8.7% improvement of stress-ng.memfd.ops_per_sec due to commit:
commit: 802f1d522d5fdaefc2b935141bc8fe03d43a99ab ("mm: page_counter: re-layout structure to reduce false sharing")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: stress-ng
on test machine: 96 threads Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 192G memory
with following parameters:
nr_threads: 10%
disk: 1HDD
testtime: 60s
fs: ext4
class: os
test: memfd
cpufreq_governor: performance
ucode: 0x5003006
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 split-job --compatible job.yaml
bin/lkp run compatible-job.yaml
