You can set CPUTYPE in /etc/make.conf to have the compiler do some CPU-specific optimizations. You can also set CFLAGS/COPTFLAGS (for world/kernel) in /etc/make.conf to whatever flags the compiler supports. Don't complain if anything breaks though - you are only supposed to touch those flags if you know what you are doing. Don't expect any major (or even noticable) improvements from these settings though. -- <Insert your favourite quote here.> Erik Trulsson [EMAIL PROTECTED] _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
