Subject: [md] dc5d17a3c3: aim7.jobs-per-min -9.0% regression
Greeting,
FYI, we noticed a -9.0% regression of aim7.jobs-per-min due to commit:
commit: dc5d17a3c39b06aef866afca19245a9cfb533a79 ("md: Set prev_flush_start and flush_bio in an atomic way")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: aim7
on test machine: 88 threads Intel(R) Xeon(R) Gold 6238M CPU @ 2.10GHz with 128G memory
with following parameters:
disk: 4BRD_12G
md: RAID0
fs: xfs
test: sync_disk_rw
load: 300
cpufreq_governor: performance
ucode: 0x5003006
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:
