You know what the machine is going to do - so l= et it=20 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 fi= le=20 system. Btw, when doing a copy or move test to prime the fs - copy from the sam= e type=20 of filesystem or the numbers are skewed.
