Subject: [xfs] 79b54d9bfc: aim7.jobs-per-min -2.8% regression
Greeting,
FYI, we noticed a -2.8% regression of aim7.jobs-per-min due to commit:
commit: 79b54d9bfcdcd0a431bb3501013885f8f00cdb43 ("xfs: use bios directly to write log buffers")
https://kernel.googlesource.com/pub/scm/linux/kernel/git/torvalds/linux.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: 300
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/
If you fix the issue, kindly add following tag
