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. (not
much though)

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)

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 :)
