Subject: [ipc/msg] 72d1e61108: stress-ng.msg.ops_per_sec 262.8% improvement
Greeting,
FYI, we noticed a 262.8% improvement of stress-ng.msg.ops_per_sec due to commit:
commit: 72d1e611082eda18689106a0c192f2827072713c ("ipc/msg: mitigate the lock contention with percpu counter")
https://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm.git mm-everything
in testcase: stress-ng
on test machine: 96 threads 2 sockets Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz (Cascade Lake) with 512G memory
with following parameters:
nr_threads: 100%
testtime: 60s
sc_pid_max: 4194304

To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
sudo bin/lkp install job.yaml # job file is attached in this email
bin/lkp split-job --compatible job.yaml # generate the yaml file for lkp run
sudo bin/lkp run generated-yaml-file
# if come across any failure that blocks the test,
# please remove ~/.lkp and /lkp dir to run from a clean state.
