Ok, so I cheated with -DNOPROFILE and I have a somewhat modified
bsd.subdir.mk that parallelizes some subdir builds in the "building
everything" phase of the make. This is with a dual 466 Celeron, 128M
66Mhz FSB, no overclocking, Abit BP6. I'm using -pipe in
/etc/make.conf and /usr/src, /usr/obj and /tmp are all on a striped
vinum volume that resides on 2 IBM 9G 7200RPM SCSI drives with
softupdates.
I like the price compared to the 4 way Xeon!
