Subject: [mm] 4e2c82a409: will-it-scale.per_process_ops 1894.6% improvement
Greeting,
FYI, we noticed a 1894.6% improvement of will-it-scale.per_process_ops due to commit:
commit: 4e2c82a40911c19419349918e675aa202b113b4d ("[PATCH v5 3/3] mm: adjust vm_committed_as_batch according to vm overcommit policy")
url: https://github.com/0day-ci/linux/commits/Feng-Tang/make-vm_committed_as_batch-aware-of-vm-overcommit-policy/20200621-153906
in testcase: will-it-scale
on test machine: 104 threads Skylake with 192G memory
with following parameters:
nr_task: 100%
mode: process
test: mmap1
cpufreq_governor: performance
ucode: 0x2000065
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
