I've added graphs showing Altivec performance. The MP scaling on the PS3 is _much_ better with Altivec than without it. I suspect it has something to with the interaction between the dual-thread dispatch and the VSU pipeline. (I'd always thought that SMT / hyper-threading was a crock, but at least in this one case it pays off).
