	I think it has more to do with the debug options as I can see from
your CONFIG file.  How long does your buildkernel take?  Also, is there
something to time the buildworld process since I notice it has a start
time but it doesn't tell you at the end, how long it takes exactly.  I
basically do a script /home/root/mw.out and then do the make buildworld
under that.  All I can tell is that the buildworld started at:
Script started on Sat Feb 28 01:53:16 2004
You have mail.^M
root_at_bigbang [1:53am][/usr/src] >> make -j4 u^H^[[Kbuildworld^M^M
and then it ended at:
===> usr.sbin/zzz^M
gzip -cn /usr/src/usr.sbin/zzz/zzz.8 > zzz.8.gz^M

	The original Willimette P4 was pretty poor in performance but I
think the Northwood is better.  I'm running a Northwood Mobile P4 2.6Ghz
CPU which is the maximum this machine supports so I don't really have a
choice and this is a high-end notebook at the time as it pretty much has
the same specs as the Dell Precision M50 with 2GB Memory which I did by
changing the HD, video card and also the CPU and memory.  My desktop runs
on a P4-3.2C with HyperThreading and 2GB and 7200rpm drives as well and
that machine is pretty fast.
