Subject: [xfs] 32678f1513: aim7.jobs-per-min -5.6% regression
Greeting,
FYI, we noticed a -5.6% regression of aim7.jobs-per-min due to commit:
commit: 32678f151338b9a321e9e27139a63c81f353acb7 ("[PATCH 1/4] xfs: detect self referencing btree sibling pointers")
url: https://github.com/intel-lab-lkp/linux/commits/Dave-Chinner/xfs-fix-random-format-verification-issues/20220502-162206
base: https://git.kernel.org/cgit/fs/xfs/xfs-linux.git for-next
patch link: https://lore.kernel.org/linux-xfs/20220502082018.1076561-2-david@fromorbit.com
in testcase: aim7
on test machine: 88 threads 2 sockets Intel(R) Xeon(R) Gold 6238M CPU @ 2.10GHz with 128G memory
with following parameters:
disk: 4BRD_12G
md: RAID0
fs: xfs
test: disk_wrt
load: 3000
cpufreq_governor: performance
ucode: 0x500320a
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/
If you fix the issue, kindly add following tag
Reported-by: kernel test robot <oliver.sang@...el.com>
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.
