Subject: [btrfs] 259c4b96d7:
fxmark.ssd_btrfs_dbench_client_4_bufferedio.works/sec 15.8% improvement
Greeting,
FYI, we noticed a 15.8% improvement of fxmark.ssd_btrfs_dbench_client_4_bufferedio.works/sec due to commit:
commit: 259c4b96d78dda8477a3ac21d6b3cf0eb9f75c8b ("btrfs: stop doing unnecessary log updates during a rename")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
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: dbench_client
fstype: btrfs
directio: bufferedio
cpufreq_governor: performance
ucode: 0xd000331
test-description: FxMark is a filesystem benchmark that test multicore scalability.
test-url: https://github.com/sslab-gatech/fxmark
Details are as below:
-------------------------------------------------------------------------------------------------->
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.
