Comment (or remove) these lines in your kernel config: makeoptions DEBUG=-g options DDB options INVARIANTS options INVARIANT_SUPPORT options WITNESS options WITNESS_SKIPSPIN You should also add the following to /etc/make.conf: NOPROFILE=true You can find info on how to set maximum optimizations with gcc 3.2 here: http://www.freehackers.org/gentoo/gccflags/flag_gcc3opt.html (Originally written for gentoo linux, but should work with FreeBSD too). A warning though, NEVER compile world and your kernel using all these flags unless you are prepared to reinstall. My system failed once simply because I used CFLAGS = "-O3 -pipe" instead of "-O2 -pipe". You will probably be able to compile most ports with these flags though, back when I ran gentoo I was able to compile 99% of all applications with these. //David Holm On Thu, 09 Jan 2003 11:22:39 -0800 Joe Laughlin <joe@removethis.rainbowsheep.net> wrote: > In the UPDATING file, the following is noted: > > FreeBSD 5.0-CURRENT has many debugging features turned on, in > both the kernel and userland.
