Subject: [linus:master] [mm] f1a7941243: unixbench.score -19.2% regression
please be noted we reported
"[linux-next:master] [mm] f1a7941243: unixbench.score -5.1% regression"
on
https://lore.kernel.org/all/202212051324.182a6363-yujie.liu@intel.com/
when this commit was on linux-next
now after this commit was already merged to mainline, by other options in
unixbench testing, we noticed regression is still existing.
report again FYI. below is the full report.
Greeting,
FYI, we noticed a -19.2% regression of unixbench.score due to commit:
commit: f1a7941243c102a44e8847e3b94ff4ff3ec56f25 ("mm: convert mm's rss stats into percpu_counter")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: unixbench
on test machine: 128 threads 4 sockets Intel(R) Xeon(R) Gold 6338 CPU @ 2.00GHz (Ice Lake) with 256G memory
with following parameters:
runtime: 300s
nr_task: 30%
test: spawn
cpufreq_governor: performance
test-description: UnixBench is the original BYTE UNIX benchmark suite aims to test performance of Unix-like system.
test-url: https://github.com/kdlucas/byte-unixbench
In addition to that, the commit also has significant impact on the following tests:
+------------------+--------------------------------------------------------------------------------------------+

| Link: https://lore.kernel.org/oe-lkp/202301301057.e55dad5b-oliver.sang@intel.com
Details are as below:
-------------------------------------------------------------------------------------------------->
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.
