no, fs testing is easy. You know what the machine is going to do - so let it 
do it and measure the time it needs. Easy.

That way I found that reiser4+lzo is the best one *for me* and xfs the worst.

But I am sure a lot of people have scenarios where xfs is the best. Or ext4.

And if you don't care about barriers, jfs might be a good choice.

It depends on the stuff you want to do and what do you expect from a file 
system.

Btw, when doing a copy or move test to prime the fs - copy from the same type 
of filesystem or the numbers are skewed.
