I'm about to setup mail server. It will store user's mails into Maildir format(postfix, dovecot). Storage is ~2TB on LVM w/snapshots.
Now I was thinking about reiserfs as filesystem, but I heard it does not performs so well as rumoured.
So will You recommend me reiserfs or ext3. No other option I accept. Please back up Your recommendation with some tests results(web links) or at least personal experience.
