Subject: [memcg] fd25a9e0e2: fio.write_iops 47.8% improvement
Greeting,
FYI, we noticed a 47.8% improvement of fio.write_iops due to commit:
commit: fd25a9e0e23b995fd0ba5e2f00a1099452cbc3cf ("memcg: unify memcg stat flushing")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: fio-basic
on test machine: 96 threads 2 sockets Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 512G memory
with following parameters:
disk: 2pmem
fs: ext4
runtime: 200s
nr_task: 50%
time_based: tb
rw: randrw
bs: 4k
ioengine: sync
test_size: 200G
cpufreq_governor: performance
ucode: 0x500320a
test-description: Fio is a tool that will spawn a number of threads or processes doing a particular type of I/O action as specified by the user.
test-url: https://github.com/axboe/fio
In addition to that, the commit also has significant impact on the following tests:

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.
