12、很大，原因尚在查。另外我测了-rw=randrw -rwmi*read=100 ，看起来读占了100%，应该等同于-rw=randread随机读模式，但是结果不同相差很大。两种指令：指令结果fio -filename=/dev/sdf -direct=1 -iodepth 1024 -thread -rw=randrw -rwmi*read=100 -ioengine=libaio -bs=1024k -size=50G -numjobs=30 -runtime=10 -group_reporting -name=mytestbw=391200KB/s, iops=382，lat avg=4969.31fio -filename=/dev/sdf -direct=1 -iodepth 1024 -thread -rw=randread -ioengine=libaio -bs=1024k -size=50G -numjobs=30 -runtime=10 -group_reporting -name=mytestbw=699903KB/s, iops=683, lat avg=43743.14
