When it comes to a SOHO server, yeah, I'd say reiserfs isn't going to gain
him much. Despite ext2's drawbacks (lacking journaling), I've still never
lost a filesystem on it that wasn't related to hardware blowing up.

I did go and check out their benchmarks just now though, and the results
aren't as straightforward as I remembered -- reiser does appear to
outperform ext2 in some situations. However, I'll stick by my conclusion
until someone shows me benchmarks of a reiserfs mail spool saving them a
measurable amount of time while pushing 300 msgs/day. :)
