5.为了理解存储性能使用小与大混合的随机I/O工作量:
[oracle@jyrac1 bin]$ ./orion -run normal -testname jytest
ORION: ORacle IO Numbers -- Version 11.2.0.4.0
jytest_20161012_1923
Calibration will take approximately 113 minutes.
Using a large value for -cache_size may take longer.
Maximum Large MBPS=124.02 @ Small=0 and Large=6
