Subject: [ext4, jbd2] 7b97d868b7: aim7.jobs-per-min 21.9% improvement
Greeting,
FYI, we noticed a 21.9% improvement of aim7.jobs-per-min due to commit:
commit: 7b97d868b7ab2448859668de9222b8af43f76e78 ("ext4, jbd2: ensure panic by fix a race between jbd2 abort and ext4 error handlers")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: aim7
on test machine: 72 threads Intel(R) Xeon(R) Gold 6139 CPU @ 2.30GHz with 128G memory
with following parameters:
disk: 4BRD_12G
md: RAID0
fs: ext4
test: disk_cp
load: 3000
cpufreq_governor: performance
ucode: 0x2006906
test-description: AIM7 is a traditional UNIX system level benchmark suite which is used to test and measure the performance of multiuser system.
