We use Intel Core2uo-CPUs. Which parameter should we use (nocona, prescott...) ? gcc 3.4.3 has no specific tuning for Core2 Duo, if for no other reason than the release was made before the processors became available. My guess would be that you will get the best results with -mtune=nocona. But it is only a guess. Ian
