Subject: Re: [RFC PATCH 3/3][RESEND] xfs: mark the inode for high-res
timestamp update in getattr
Hello,
kernel test robot noticed a -4.8% regression of fsmark.files_per_sec on:
commit: 219c0ed2b1f5d2ad921dc206b7b23a0e29e5c516 ("[RFC PATCH 3/3][RESEND] xfs: mark the inode for high-res timestamp update in getattr")
url: https://github.com/intel-lab-lkp/linux/commits/Jeff-Layton/fs-add-infrastructure-for-opportunistic-high-res-ctime-mtime-updates/20230411-223803
base: https://git.kernel.org/cgit/fs/xfs/xfs-linux.git for-next
patch link: https://lore.kernel.org/all/20230411143702.64495-4-jlayton@kernel.org/
patch subject: [RFC PATCH 3/3][RESEND] xfs: mark the inode for high-res timestamp update in getattr
testcase: fsmark
test machine: 96 threads 2 sockets (Ice Lake) with 256G memory
parameters:
iterations: 1x
nr_threads: 1t
disk: 1BRD_32G
fs: xfs
fs2: nfsv4
filesize: 4K
test_size: 4G
sync_method: fsyncBeforeClose
nr_files_per_directory: 1fpd
cpufreq_governor: performance
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.
