Subject: [lkp-robot] [mm, mlock, vmscan] ae938e2990: reaim.jobs_per_min
-12.1% regression
Greeting,
FYI, we noticed a -12.1% regression of reaim.jobs_per_min due to commit:
commit: ae938e2990fbfb4e7ed92e4a6f494a47c418dde7 ("mm, mlock, vmscan: no more skipping pagevecs")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
in testcase: reaim
on test machine: 56 threads Intel(R) Xeon(R) CPU E5-2695 v3 @ 2.30GHz with 256G memory
with following parameters:
runtime: 300s
nr_task: 1000
test: page_test
cpufreq_governor: performance
test-description: REAIM is an updated and improved version of AIM 7 benchmark.
test-url: https://sourceforge.net/projects/re-aim-7/
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
