IOzone filesystem benchmark

[parisa_k]

hi,
I`m not sure whether here is a right place for asking this question or not...if not, I`d be thankful if you could tell me where should I ask it....

as you may know, IOzone is a benchmark for measuring file system performance (although it`s not just for working under linux, but I`m using it under linux OS)

I could successfully run this benchmark on my systems and it gave some results about my system`s current file system`s performance....

but the question is that:
----------------------------------
how can I use it for comparing different file systems?
and I also can`t understand how to draw graphs form output result automatically..........

thanks
