( my apologies for pursuing the OT....)

I can't speak for Fedora, i haven't bothered using it. I can tell you , though,
that ext3's journal is prey to memory hungry processes (like VMWare server) -
user level app uses lots of memory, the fs doesn't have enough to cache/journal
and you hit the ground very fast and very hard. There are some sysctl you can
use to postpone this (at the expense of usable memory). 

Other than that, i can't say ext3 is that bad.

But yeah, I still haven't found enough reasons to move back to Linux from FBSD.
