That depends on processor architecture rather than clock frequency. Have a look at dmesg output - for example, Intel Celeron 400Mhz is a 686 class processor (I686_CPU in the kernel configuration file): % dmesg % [...] % CPU: Pentium II/Pentium II Xeon/Celeron (400.91-MHz 686-class CPU) % [...] > Second, is it safe to do a buildworld with -O3?

In any other situation just stick with the defaults, which on 6.2-RELEASE for my Celeron are: # (cd /usr/src && make -V CFLAGS ) -O2 -fno-strict-aliasing -pipe -march=pentiumpro Note that '-march=pentiumpro' comes from setting 'CPUTYPE=i686' in /etc/make.conf (examples in /usr/share/examples/etc/make.conf).
