The 5.x series was a "transition" release, to ease the pain between 4.x
and 6.x. I would recommend going up to 6.0 (or 6.1, But I have not yet
tested it) Doing a fresh install would probably be in your best
interest. Also running a custom kernel will ease some of the overhead,
if you aren't already doing that. Remove anything from the kernel you do
not use, etc.. There are numerous documents for doing this. The freebsd
handbook is a excellent resource for both newbies and seasoned system
admins. (http://www.freebsd.org/handbook) The output of `ps uxaww` will
give us more of an idea of what you can get rid of as far as running
daemons. Hope this helps.
