Is this value with tails or without tails?
One would mount a reiser-video partition with "notails" and have a lot less 
cpu-load...

The high values for XFS i can understand, but i wonder why JFS is so good, in 
a ct' magazin jfs performed so poorly against reiser, only xfs was better and 
this also only with large files.

Fragementation plays a major role too - a fresh filesystem might perform much 
faster than a partition that has severally been filled up with a mixture of 
small and large files and later (maybe) only the large ones being deleted.

XFS stores these in separate regions i heard and thus avoids some of this.
