I'm curious what you feel those weaknesses are.  The recent addition of
XFS back into a more mainstream position in the RHEL kernel as of their
5.4 update greatly expands where I can use it now, have been heavily
revisiting it since that release.  I've already noted how well it does
on sequential read/write tasks relative to ext3, and it looks like the
main downsides I used to worry about with it (mainly crash recovery
issues) were also squashed in recent years.
