Subject: [f2fs] b5d15199a2: stress-ng.link.ops_per_sec 175.3% improvement
Greeting,
FYI, we noticed a 175.3% improvement of stress-ng.link.ops_per_sec due to commit:
commit: b5d15199a26f6dce624b43c82764cdb3827e7c89 ("f2fs: set checkpoint_merge by default")
https://git.kernel.org/cgit/linux/kernel/git/jaegeuk/f2fs.git dev
in testcase: stress-ng
on test machine: 48 threads Intel(R) Xeon(R) CPU E5-2697 v2 @ 2.70GHz with 112G memory
with following parameters:
nr_threads: 10%
disk: 1HDD
testtime: 60s
fs: f2fs
class: filesystem
test: link
cpufreq_governor: performance
ucode: 0x42e
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 split-job --compatible job.yaml
bin/lkp run compatible-job.yaml
