Examples of running Iozone:
The simplest way to get started is to try the automatic mode.
Iozone –a
If you wish to generate graphs then you may wish to turn on Excel mode.
Iozone –Ra ( Output can be imported using space and tab delimited)
Or
Iozone –Rab output.wks ( Output file “output.wks” is a binary format spreadsheet)
If you have more than 512 Mbytes of memory then you need to increase the maximum file size to
a larger value. For example if your system has 1 Gbyte of memory then you would want to try something
like:
Iozone –Ra –g 2G
If you only care about read/write and do not wish to spend the time to perform all of the tests, then
you may wish to limit the testing like:
Iozone –Ra –g 2G –i 0 –i 1
If you are running Iozone over NFS on an NFS client then you may wish to use:
Iozone –Rac
