I'm no compiler expert, but prescott and nocona are Net-Burst architectures. Core(2) is a pentium-m successor, which was a completely different (x86) architecture, so optimizations for netburst won't have a positive effect, if they work at all. I use CPUTYPE?=pentium-m, but I've never done any comparisions to binaries compiled without CPUTYPE. After several years observation with CPUTYPE I guess the improovement ist smaller than ever these days, and until now it was rarely mesureable. -Harry -- OmniSEC - UNIX und Windows Netzwerke - Sicher Harald Schmalzbauer Flintsbacher Str. 3 80686 München +49 (0) 89 18947781 +49 (0) 160 93860101 _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
