Subject: [btrfs] c7edee49c1: fxmark.ssd_btrfs_MWCL_4_bufferedio.works/sec
18.0% improvement
Greeting,
FYI, we noticed a 18.0% improvement of fxmark.ssd_btrfs_MWCL_4_bufferedio.works/sec due to commit:
commit: c7edee49c1935f66c07c5c2c1aa98a599e4a11ad ("btrfs: rework inode creation to fix several issues")
linux-devel devel-catchup-20220304-125122
in testcase: fxmark
on test machine: 128 threads 2 sockets Intel(R) Xeon(R) Platinum 8358 CPU @ 2.60GHz with 128G memory
with following parameters:
disk: 1SSD
media: ssd
test: MWCL
fstype: btrfs
directio: bufferedio
cpufreq_governor: performance
ucode: 0xd000331
test-description: FxMark is a filesystem benchmark that test multicore scalability.

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.
