Subject: [lkp-robot] [MD] 5a409b4f56: aim7.jobs-per-min -27.5% regression
Greeting,
FYI, we noticed a -27.5% regression of aim7.jobs-per-min due to commit:
commit: 5a409b4f56d50b212334f338cb8465d65550cd85 ("MD: fix lock contention for flush bios")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
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: xfs
test: sync_disk_rw
load: 600
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/
