| |
FYI, we noticed fio.write_bw_MBps -10.5% regression due to commit:
commit 074e46e1aded0ac0474a5db4d50d514d9dc42e78 ("writeback: throttle buffered writeback") https://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux-block.git wb-buf-throttle
in testcase: fio-basic on test machine: lkp-bdw-ep2: threads Broadwell-EP with 128G memory with following conditions: bs=4k/cpufreq_governor=performance/disk=1SSD/fs=xfs/ioengine=sync/nr_task=8/runtime=300/rw=write/test_size=512g
Details are as below: -------------------------------------------------------------------------------------------------->
