Subject: [linux-next:master] [block/mq] 574e7779cf: fio.write_iops -72.9% regression
Date: Wed, 31 Jan 2024 23:42:11 +0800 [thread overview]
Message-ID: <202401312320.a335db14-oliver.sang@intel.com> (raw)
Hello,
kernel test robot noticed a -72.9% regression of fio.write_iops on:
commit: 574e7779cf583171acb5bf6365047bb0941b387c ("block/mq-deadline: use separate insertion lists")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
testcase: fio-basic
test machine: 64 threads 2 sockets Intel(R) Xeon(R) Gold 6346 CPU @ 3.10GHz (Ice Lake) with 256G memory
parameters:
runtime: 300s
disk: 1HDD
fs: xfs
nr_task: 100%
test_size: 128G
rw: write
bs: 4k
ioengine: io_uring
direct: direct
cpufreq_governor: performance
