Subject: [btrfs] 8d47a0d8f7: fio.write_bw_MBps -28.6% regression
Greeting,
FYI, we noticed a -28.6% regression of fio.write_bw_MBps due to commit:
commit: 8d47a0d8f7947422dd359ac8e462687f81a7a137 ("btrfs: Do mandatory tree block check before submitting bio")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: fio-basic
on test machine: 72 threads Intel(R) Xeon(R) CPU E5-2699 v3 @ 2.30GHz with 256G memory
with following parameters:
disk: 2pmem
fs: btrfs
runtime: 200s
nr_task: 50%
time_based: tb
rw: randwrite
bs: 4k
ioengine: libaio
test_size: 100G
cpufreq_governor: performance
ucode: 0x3d
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:
