解压即可使用
# gzip orion_linux_x86-64.gz

测异步IO时需要libaio库
# export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib64
# echo $LD_LIBRARY_PATH
:/opt/oracle/product/10.2.0/lib:/usr/lib64

创建配置文件mytest.lun,列出要测试的分区即可. 注意文件名前缀要跟下面的 testname一致
# vi mytest.lun

查看mytest.jun内容
# cat mytest.lun
/dev/sda2

先来个simple test
# ./orion_linux_x86-64 -run simple -testname mytest -num_disks 8

查看测试结果
# cat mytest_20081111_1431_summary.txt
ORION VERSION 11.1.0.7.0

Commandline:
-run simple -testname mytest -num_disks 8

This maps to this test:

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
ORION VERSION 11.1.0.7.0

Commandline:

最大MBPS为3.21(这么低？？)，最大IOPS为448

再测一下1M顺序读操作, 失败了, 原因不明...
# ./orion_linux_x86-64 -run advanced -testname mytest -num_disks 8 -size_small 1024 -size_large 1024 -type seq
