Where did you compile your toolkit? I would expect a compile on a G5 itself should give you a few percentage of speedup apart from the linear speed up.

Well, the 3GHz G5 roadmap (at 3GHZ by the end of late summer 2004) was stated from Steve himself. But as always, it counts when they're out, not before. And with Apple, it counts when they actually deliver, not when they're officially released. :p (although that probably holds for the top-models of AMD/Intel-based machines as well) >If IBM can keep on their POWER architecture roadmap moving towards 8 GHz >chips by the end of the decade, then the days of x86 dominance of the >desktop market may be limited. As much as I would like that to happen, forget it... do you think AMD/Intel will stand still? (well AMD maybe, after Intel has killed them...) And if the PPC would be the fastest comp on Earth, it would not count since it's not running Windows. (no flamewar please :) Sargon
