Subject: [ext4] 05c2c00f37: aim7.jobs-per-min -11.8% regression
Greeting,
FYI, we noticed a -11.8% regression of aim7.jobs-per-min due to commit:
commit: 05c2c00f3769abb9e323fcaca70d2de0b48af7ba ("ext4: protect superblock modifications with a buffer lock")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: aim7
on test machine: 88 threads Intel(R) Xeon(R) Gold 6238M CPU @ 2.10GHz with 128G memory
with following parameters:
disk: 4BRD_12G
md: RAID1
fs: ext4
test: creat-clo
load: 1000
cpufreq_governor: performance
ucode: 0x5003006
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/
In addition to that, the commit also has significant impact on the following tests:
+------------------+---------------------------------------------------------------------------+
| testcase: change | aim9: aim9.udp_test.ops_per_sec 2.1% improvement |
| test machine | 256 threads Intel(R) Genuine Intel(R) CPU 0000 @ 1.30GHz with 112G memory |
| test parameters | cpufreq_governor=performance |
| | test=all |
| | testtime=5s |
| | ucode=0xffff0190 |
+------------------+---------------------------------------------------------------------------+
If you fix the issue, kindly add following tag
