I thought the P4 added another FPU and could simultaneously execute. 
Plus can retire more instructions/clock (assuming no deleterious
branches).  Since scheduling the computes requres either ASM or a good
optimizing compiler (not yet existent), I'm not suprised that running
the same old code on a P4 doesn't show improvements.
