Subject: [ext4] 061113efe9: fio.write_iops 364.6% improvement
Greeting,
FYI, we noticed a 364.6% improvement of fio.write_iops due to commit:
commit: 061113efe99b24ac026db5aa5a72844e16318bd7 ("ext4: optimize file overwrites")
https://git.kernel.org/cgit/linux/kernel/git/tytso/ext4.git dev
in testcase: fio-basic
on test machine: 96 threads Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 256G memory
with following parameters:
disk: 2pmem
fs: ext4
mount_option: dax
runtime: 200s
nr_task: 50%
time_based: tb
rw: randwrite
bs: 4k
ioengine: sync
test_size: 200G
cpufreq_governor: performance
ucode: 0x5002f01
test-description: Fio is a tool that will spawn a number of threads or processes doing a particular type of I/O action as specified by the user.
test-url: https://github.com/axboe/fio
Details are as below:
