Subject: [btrfs] 1eb52c8bd8: fio.write_bw_MBps -46.1% regression
Greeting,
FYI, we noticed a -46.1% regression of fio.write_bw_MBps due to commit:
commit: 1eb52c8bd8d6b056caa06737242830f03777da32 ("btrfs: get rid of one layer of bios in direct I/O")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
in testcase: fio-basic
on test machine: 160 threads Intel(R) Xeon(R) CPU E7-8890 v4 @ 2.20GHz with 256G memory
with following parameters:
runtime: 300s
disk: 1SSD
fs: btrfs
nr_task: 100%
test_size: 128G
rw: write
bs: 4k
ioengine: sync
direct: direct
cpufreq_governor: performance
ucode: 0xb000038
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
If you fix the issue, kindly add following tag
Reported-by: kernel test robot <rong.a.chen@...el.com>
