Subject: [lkp-robot] [fs] 62231fd3ed: aim7.jobs-per-min 229.5% improvement
Greeting,
FYI, we noticed a 229.5% improvement of aim7.jobs-per-min due to commit:
commit: 62231fd3ed94c9d40b4e58ab14fe173f09e252da ("fs: handle inode->i_version more efficiently")
https://git.kernel.org/cgit/linux/kernel/git/jlayton/linux.git iversion-next
in testcase: aim7
on test machine: 40 threads Intel(R) Xeon(R) CPU E5-2690 v2 @ 3.00GHz with 384G memory
with following parameters:
disk: 4BRD_12G
md: RAID0
fs: xfs
test: disk_cp
load: 3000
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/
In addition to that, the commit also has significant impact on the following tests:
