Subject: [xfs] 2ed5b09b3e: aim7.jobs-per-min 13.9% improvement
Greeting,
FYI, we noticed a 13.9% improvement of aim7.jobs-per-min due to commit:
commit: 2ed5b09b3e8fc274ae8fecd6ab7c5106a364bed1 ("xfs: make inode attribute forks a permanent part of struct xfs_inode")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: aim7
on test machine: 128 threads 2 sockets Intel(R) Xeon(R) Gold 6338 CPU @ 2.00GHz (Ice Lake) with 256G memory
with following parameters:
disk: 1BRD_48G
fs: xfs
test: disk_rd
load: 9000
cpufreq_governor: performance
test-description: AIM7 is a traditional UNIX system level benchmark suite which is used to test and measure the performance of multiuser system.
test-url: https://sourceforge.net/projects/aimbench/files/aim-suite7/
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.
