Subject: [btrfs] 47876f7cef: reaim.jobs_per_min -7.3% regression
Greeting,
FYI, we noticed a -7.3% regression of reaim.jobs_per_min due to commit:
commit: 47876f7ceffa0e6af7476e052b3c061f1f2c1d9f ("btrfs: do not block inode logging for so long during transaction commit")
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: btrfs
test: disk
cpufreq_governor: performance
ucode: 0x5003003
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
Reported-by: kernel test robot <oliver.sang@...el.com>
Details are as below:
