Message-ID: <1541010174-28621-1-git-send-email-sherry.hurwitz@amd.com> (raw)
In-Reply-To: <20181023014044.15888-1-longli@linuxonhyperv.com>

Tested with fio on a 2 socket AMD EPYC based server with 128 cores and 8 nvme drives.  Comparing baseline linux-next kernel results with linux-next with this patch applied IOPS increased by 40%. 

sudo fio --bs=4k --ioengine=libaio --iodepth=16 --filename=/dev/nvme1n1:/dev/nvme2n1:/dev/nvme3n1:/dev/nvme4n1:/dev/nvme5n1:/dev/nvme6n1:/dev/nvme7n1:/dev/nvme8n1 --direct=1 --runtime=60 --numjobs=160 --rw=randread --name=test --group_reporting
