Subject: [mm] f35b5d7d67: will-it-scale.per_process_ops -95.5% regression
Hi Rik,
Please be noted that we reported
[mm] 96db82a66d: will-it-scale.per_process_ops -95.3% regression
at
https://lore.kernel.org/all/YwIoiIYo4qsYBcgd@xsang-OptiPlex-9020/
when this commit was on
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git master
now we noticed the commit has been merged to mainline and we still
observed similar test result.
We are not sure if this is an expected performance change when
switching to huge page or if it could benefit other use cases, so we
report again FYI. Please feel free to ignore the report if the test
result is just as expected. Thanks.
Greeting,
FYI, we noticed a -95.5% regression of will-it-scale.per_process_ops due to commit:
commit: f35b5d7d676e59e401690b678cd3cfec5e785c23 ("mm: align larger anonymous mappings on THP boundaries")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: will-it-scale
on test machine: 128 threads 2 sockets Intel(R) Xeon(R) Gold 6338 CPU @ 2.00GHz (Ice Lake) with 256G memory
with following parameters:
nr_task: 100%
mode: process
test: malloc1
cpufreq_governor: performance
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
In addition to that, the commit also has significant impact on the following tests:

| Reported-by: kernel test robot <yujie.liu@...el.com>
| Link: https://lore.kernel.org/r/202210181535.7144dd15-yujie.liu@intel.com
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.
