Subject: [ext4] d3b6f23f71: stress-ng.fiemap.ops_per_sec -60.5% regression
Greeting,
FYI, we noticed a -60.5% regression of stress-ng.fiemap.ops_per_sec due to commit:
commit: d3b6f23f71670007817a5d59f3fbafab2b794e8c ("ext4: move ext4_fiemap to use iomap framework")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: stress-ng
on test machine: 96 threads Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 192G memory
with following parameters:
nr_threads: 10%
disk: 1HDD
testtime: 1s
class: os
cpufreq_governor: performance
ucode: 0x500002c
fs: ext4
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
bin/lkp install job.yaml # job file is attached in this email
bin/lkp run job.yaml
