Subject: [LKP] [f2fs] 089842de57: aim7.jobs-per-min 15.4% improvement
Greeting,
FYI, we noticed a 15.4% improvement of aim7.jobs-per-min due to commit:
commit: 089842de5750f434aa016eb23f3d3a3a151083bd ("f2fs: remove codes of unused wio_mutex")
https://git.kernel.org/cgit/linux/kernel/git/jaegeuk/f2fs.git dev-test
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: RAID1
fs: f2fs
test: disk_rw
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:
