Subject: [linus:master] [btrfs] c87c299776: iozone.average_KBps 18.5%
regression
Hello,
kernel test robot noticed a 18.5% regression of iozone.average_KBps on:
commit: c87c299776e4d75bcc5559203ae2c37dc0396d80 ("btrfs: make buffered write to copy one page a time")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
[still regression on linus/master 2ba9f676d0a2e408aef14d679984c26373bf37b7]
[still regression on linux-next/master f486c8aa16b8172f63bddc70116a0c897a7f3f02]
testcase: iozone
config: x86_64-rhel-9.4
compiler: gcc-12
test machine: 8 threads 1 sockets Intel(R) Core(TM) i7-7700 CPU @ 3.60GHz (Kaby Lake) with 32G memory
parameters:
disk: 2HDD
fs: btrfs
iosched: kyber
cpufreq_governor: performance
