Subject: [btrfs] 8698fc4eb7: fio.write_iops 44.9% improvement
Greeting,
FYI, we noticed a 44.9% improvement of fio.write_iops due to commit:
commit: 8698fc4eb7884eeba29adc4193f9d05fa2bed16b ("btrfs: add btrfs_reserve_data_bytes and use it")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
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: btrfs
runtime: 200s
nr_task: 50%
time_based: tb
rw: write
bs: 2M
ioengine: sync
test_size: 100G
cpufreq_governor: performance
ucode: 0x5003003
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:
