Heh looks like I left a trailing thought...
My post wasn't saying don't use journaled filesystems, but rather
that it can be slower than non-journaled filesystems, and I don't
consider recovery time from a crash to be a factor in determining the
speed of reads and writes on the data. That being said, I think
Tom's reply on what to journal and not to journal should really put
an end to this side of the conversation.
