I had the opposite problem: I could not build the world/kernel until I set
CPUTYPE to "c3-2" (or "c3"). It was a brand new VIA EDEN-EX 1.5GHz with no
other things installed but a copy of the 7.0-RELEASE-p1 source. (I did not
have compile problems when I installed the 6.2 on a similar machine)
I set CPUTYPE in /etc/make.conf. I think it is only used by the gcc
compiler so it will probably only make a difference if you compile ports
or from source.
Compiling the kernel/world with CPUTYPE=c3-2 I think I see an improved
boot time. I do not know of other gains as the server idles most of the
time so I do not really care as long as it is stable. I never did try to
time the kernel and world builds.
