Readonly filesystem benchmark software on Linux

Question

Updated: iozone has an option -+E which could use non-iozone file to run a readonly FS benchmark test

I am working on a project which aimed at making a 2level-cached read-only filesystem, and now I need to test it's performance.

I've tried iozone, but seems that even use -i 1 it will also create a temp file, which I could not support.

Could you give me some advice about use iozone to test read-only FS? I'm really not familiar with it

Is there any benchmark software could test read-only FS?

Thanks your guys!

I highly recommend fio tool. It has a lot of options that help you mimick real world scenarios. I haven't used the readonly option myself but it has the capability.
