iops测试

1、4k随机写

fio -filename=/mnt/cephfs/fio.file -direct=1 -iodepth=32 -thread -rw=randwrite -ioengine=libaio -bs=4k -size=200m -numjobs=2 -runtime=60 -group_reporting  -name=Write_PPS_Testing

2、4k随机读

fio -filename=/mnt/cephfs/fio.file -direct=1 -iodepth=32 -thread -rw=randread -ioengine=libaio -bs=4k -size=200m -numjobs=2 -runtime=60 -group_reporting  -name=Write_PPS_Testing

3、4看随机汇合读写

fio -filename=/mnt/cephfs/fio.file -direct=1 -iodepth=32 -thread -rw=randrw -rwmixread=70 -ioengine=libaio -bs=4k -size=200m -numjobs=2 -runtime=60 -group_reporting  -name=Write_PPS_Testing
# -rwmixread=70 表示du操作占比70%

吞吐量测试

1、1M顺序写

fio -filename=/mnt/cephfs/fio.file -direct=1 -iodepth=32 -thread -rw=write -ioengine=libaio -bs=1M -size=200m -numjobs=2 -runtime=60 -group_reporting  -name=Write_PPS_Testing
