Can't you use GCC3 and use the flag -faltivec? It is slows it down a
ton because it can't use the precompiled headers, but it also seems to
deliver better performance on my G4.

Is there away to optimize Cocoa Apps for the velocity engine (AltiVec)?
Or is it already done for us (I doubt it, but i still hope :)
I guess Cocoa routines are (at least partly) optimized for Altivec. But
to
optimize your own computations, I think there's no other way than
explicit
use of Altivec functions.
To get started with Altivec, you may take a look at this article on
O'Reilly
network : <

(and then, of course, you should visit Apple's Altivec home page :
