Subject: [LKP] [f2fs] 853137cef4: fsmark.files_per_sec 40.1% improvement
Greeting,
FYI, we noticed a 40.1% improvement of fsmark.files_per_sec due to commit:
commit: 853137cef46ccc490e6fd4b160a1c252d6459842 ("f2fs: fix performance issue observed with multi-thread sequential read")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: fsmark
on test machine: 48 threads Intel(R) Xeon(R) CPU E5-2697 v2 @ 2.70GHz with 64G memory
with following parameters:
iterations: 1x
nr_threads: 64t
disk: 1BRD_48G
fs: f2fs
filesize: 4M
test_size: 40G
sync_method: fsyncBeforeClose
ucode: 0x42d
cpufreq_governor: performance
test-description: The fsmark is a file system benchmark to test synchronous write workloads, for example, mail servers workload.
test-url: https://sourceforge.net/projects/fsmark/
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
