Subject: [linus:master] [mm] 0ba09b1733: will-it-scale.per_thread_ops -21.1%
regression in mmap1 benchmark
Greetings,
Please note that we reported a regression in will-it-scale malloc1
benchmark on below commit
f35b5d7d676e ("mm: align larger anonymous mappings on THP boundaries")
at
https://lore.kernel.org/all/202210181535.7144dd15-yujie.liu@intel.com/
and Nathan reported a kbuild slowdown under clang toolchain at
https://lore.kernel.org/all/Y1DNQaoPWxE+rGce@dev-arch.thelio-3990X/
That commit was finally reverted.
When we tested the revert commit, the score in malloc1 benchmark
recovered, but we observed another regression in mmap1 benchmark.
"Yin, Fengwei" helped to check and got below clues:
1. The regression is related with the VMA merge with prev/next
VMA when doing mmap.
2. Before the patch reverted, almost all the VMA for 128M mapping
can't be merged with prev/next VMA. So always create new VMA.
With the patch reverted, most VMA for 128 mapping can be merged.
It looks like VMA merging introduce more latency comparing to
creating new VMA.
3. If force to create new VMA with patch reverted, the result of
mmap1_thread is restored.
4. The thp_get_unmapped_area() adds a padding to request mapping
length. The padding is 2M in general. I believe this padding
break VMA merging behavior.
5. No idea about why the difference of the two path (VMA merging
vs New VMA) is not shown in perf data
Please check below report for details.
FYI, we noticed a -21.1% regression of will-it-scale.per_thread_ops due to commit:
commit: 0ba09b1733878afe838fe35c310715fda3d46428 ("Revert "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: 104 threads 2 sockets (Skylake) with 192G memory
with following parameters:
nr_task: 50%
mode: thread
test: mmap1
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.

If you fix the issue, kindly add following tag
| Reported-by: kernel test robot <yujie.liu@...el.com>
| Link: https://lore.kernel.org/oe-lkp/202212151657.5d11a672-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.
