I want to set it up as a sort of test machine. There does not seem to be a specific setting for 'cpu-type' or 'march' for this machine. I have notices on some Linux forums that they recommend using the 'native' keyword; i.e., "march=native" in the 'make.conf' file to get the most optimization out of the CPU. Would that be correct for FreeBSD also? Would it also be appropriate for other CPUs as well?
