Greeting,
FYI, we noticed a 19.1% improvement of fsmark.files_per_sec due to commit:
commit: 58f258f65267542959487dbe8b5641754411843d ("Revert "nfsd: skip some unnecessary stats in the v4 case"")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: fsmark
on test machine: 128 threads 2 sockets Intel(R) Xeon(R) Gold 6338 CPU @ 2.00GHz with 256G memory
with following parameters:
iterations: 1x
nr_threads: 1t
disk: 1BRD_32G
fs: ext4
fs2: nfsv4
filesize: 4K
test_size: 4G
sync_method: fsyncBeforeClose
nr_files_per_directory: 1fpd
cpufreq_governor: performance
ucode: 0xd000280
test-description: The fsmark is a file system benchmark to test synchronous write workloads, for example, mail servers workload.
test-url: https://sourceforge.net/projects/fsmark/
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.
