6-CURRENT unbelievably slow?

From: Joe Marcus Clarke <marcus_at_FreeBSD.org>
Date: Wed, 10 Nov 2004 16:01:35 -0500
I've been using -CURRENT for a long time now (from early 5.X up to 6.X),
and even with WITNESS and INVARIANTS things didn't seem this slow.  I
have a P4 2.4 GHz machine with 2 GB of RAM running a very recent
6-CURRENT:

FreeBSD fugu.marcuscom.com 6.0-CURRENT FreeBSD 6.0-CURRENT #11: Wed Nov
10 01:03:33 EST 2004
gnome_at_fugu.marcuscom.com:/space2/obj/usr/src/sys/FUGU  i386

(The version prior to this from October 14 was fine), and it takes
around _8 hours_ to do a make world (this is my GNOME Tinderbox
machine).  The disk on which the build is taking place is an SATA-150
drive, and the system drive is a U320 SCSI disk on an mpt controller.
There is nothing else happening on this system while it builds, and the
build is happening normally (i.e. not through NFS, nullfs, etc.).

Attached are my dmesg and my kernel config.  Nothing has changed
configuration or hardware wise between when performance was good
(October 14 build) and now (November 10 build).  I have userland malloc
debugging disabled with /etc/malloc.conf -> ajH.

Any help would be most appreciated since I'd like to kick out a new
batch of GNOME packages.  Thanks.
