Once you have, edit /etc/make.conf and add the line: CFLAGS=3D -ffast-math -pipe -march=3Dpentium -O3 That's about as good as you can optimize it. This line is for 586 processors (Pentium, AmdK6, Cyrix6x86), so if you want to use it on a 686 (PentiumPro) change march=3Dpentium to read march=3Dpentiumpro. Well actually, don't blindly type in this information. Look at man gcc to see optimization settings. Then recompile everything (this will take a while). Once the kernel has been recompiled (this is a separate step), reboot. I suggest you read www.freebsddiary.org for more information about make world, if you haven't already.
