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=20 compiler so it will probably only make a difference if you compile ports=20 or from source. Compiling the kernel/world with CPUTYPE=3Dc3-2 I think I see an improved=20 boot time. I do not know of other gains as the server idles most of the=20 time so I do not really care as long as it is stable. I never did try to=20 time the kernel and world builds. :-) Torben Medmindre andet er angivet ovenfor: / Unless Otherwise Stated Above: IBM Danmark A/S Nym=F8llevej 91 2800 Kongens Lyngby, Danmark CVR nr.: 65305216=20
