Hi;
After switching ext3 to xfs, i realize system starts to _really_ unresponsive
and extracting tarballs, copying or deleting files or checking out svn
repositories are really slow, so i basically try to measure some for both xfs
and ext3 with same computer, same kernel (2.6.18.6), same disk, here are the
results
* between all tests i dropped caches
* i already tried to change block device's scheduler to as, noop and cfq,
nothing really changes
* i already tried 2.6.20-rc5 and 2.6.20-rc5.1.rt8.0085 which Ingo provides but
again nothing really changes

I'm not sure these are normal numbers or its a regression (i'm just starting
to use XFS) so any hints will be appreciated.
Cheers
