用fio测试IO性能

# 随机写 测试IOPS
fio -rw=randwrite -bs=4k -runtime=60 -iodepth 1 -numjobs=4 -size=10G -filename /disk1/test1 -ioengine libaio -direct=1 -group_reporting -name rand_write

# 顺序写 测试写带宽
fio -rw=write -bs=1m -runtime=60 -iodepth 1 -numjobs=4 -size=10G -filename /disk1/test1 -ioengine libaio -direct=1 -group_reporting -name seq_write

# 随机读 测试IOPS
fio -readonly -rw=randread -bs=4k -runtime=60 -iodepth 1 -numjobs=8 -size=10G -filename /disk1/test1 -ioengine libaio -direct=1 -group_reporting -name rand_read

####顺序读
fio -readonly -rw=read -bs=1m -runtime=60 -iodepth 1 -numjobs=8 -size=10G -filename /disk1/test1 -ioengine libaio -direct=1 -group_reporting -name seq_read

####混合随机读写
fio -rw=randrw -rwmixread=70 -bs=16k -runtime=60 -iodepth 1 -numjobs=8 -size=10G -filename /disk1/test1 -ioengine libaio -direct=1 -group_reporting -name mix_randrw
