Subject: [btrfs] e076ab2a2c: fio.write_iops -18.3% regression
Greeting,
FYI, we noticed a -18.3% regression of fio.write_iops due to commit:
commit: e076ab2a2ca70a0270232067cd49f76cd92efe64 ("btrfs: shrink delalloc pages instead of full inodes")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: fio-basic
on test machine: 192 threads Intel(R) Xeon(R) CPU @ 2.20GHz with 192G memory
with following parameters:
disk: 1SSD
fs: btrfs
runtime: 300s
nr_task: 8
rw: randwrite
bs: 4k
ioengine: sync
test_size: 256g
cpufreq_governor: performance
ucode: 0x4003003
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.
