I have not seen anyone doing that on Linux in an automated fashion (e.g running iozone automated every time a new 2.6.x.rc on a half a dozen of the fs - simply to verify that things had not gotten drastically worse on a particular fs due to a bug or sideffect of a global VFS change).

Yes, we definately need that.

Andrew Morton is saying that iozone does things real apps don't do, that is, it dirties mmap'd pages enough to swamp the machine.

Do you guys agree or disagree with that?

Reiser4 needs iozone optimization work which we haven't bothered with yet.
