Subject: [xfs] 2def2845cc: reaim.jobs_per_min -6.3% regression
Greeting,
FYI, we noticed a -6.3% regression of reaim.jobs_per_min due to commit:
commit: 2def2845cc33390e39b51440508043e4981e10ee ("xfs: don't allow log IO to be throttled")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: reaim
on test machine: 96 threads Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 256G memory
with following parameters:
runtime: 300s
nr_task: 100
disk: 1HDD
fs: xfs
test: disk
cpufreq_governor: performance
ucode: 0x5002f01
test-description: REAIM is an updated and improved version of AIM 7 benchmark.
test-url: https://sourceforge.net/projects/re-aim-7/
If you fix the issue, kindly add following tag
