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)=20 architecture, so optimizations for netburst won't have a positive effect, i= f=20 they work at all. I use CPUTYPE?=3Dpentium-m, but I've never done any comparisions to binarie= s=20 compiled without CPUTYPE. After several years observation with CPUTYPE I=20 guess the improovement ist smaller than ever these days, and until now it w= as=20 rarely mesureable. =2DHarry =2D-=20 OmniSEC - UNIX und Windows Netzwerke - Sicher Harald Schmalzbauer =46lintsbacher Str. 3 80686 M=C3=BCnchen +49 (0) 89 18947781 +49 (0) 160 93860101
