Linux基础教程:关于Linux IO性能测试的实验(3)

Maximum Large MBPS=56.97 @ Small=0 and Large=7

Maximum Small IOPS=442 @ Small=40 and Large=0

Minimum Small Latency=14.62 @ Small=1 and Large=0

最大MBPS为56.97,最大IOPS为442

再测一下8k随机读操作

# 。/orion_linux_x86-64 -run advanced -testname mytest -num_disks 8 -size_small 8 -size_large 8 -type rand &

看看结果

# cat mytest_20081111_1519_summary.txt
