I have been a big fan of XFS ever since SGI made the first public code
drop way back. I was frustrated with the length of time it took for
ext2 to recover after a system crash/hang, and the periodic forced
fsck during bootup. For those reasons I skipped over ext3 entirely and
haven't heard many good things about its performance.

But recently I've tried ext4 and I am reasonably impressed with the
performance. I installed Ubuntu 10.04 on my laptop and used XFS. I
figured that Ubuntu had abandoned the "30 second bootup" that they
were so proud of in the past... until I hosed my system and
reinstalled and decided to try ext4.... and wow, the system boots
really fast, and overall the performance does feel faster than with
XFS (much to my amazement)

Ext4 still has the very frustrating forced fsck every so often, though
(I'm not sure what the default setting is... I think maybe every 20
mounts?).

(I was sold on moving everything to ext4 right up until the first time
my Ubuntu system did its forced fsck ... not really something I want
happening on a Myth box that wakes itself up right before recordings
start...)
