I'm familiar with Gentoo and several compiler options, but none of these 
things apply here. openssl uses hand-optimized assembly code for some 
algorithms. Since the peak performance for large data size is 
approximately the same, I'd point to other optimizations like memory 
accesses. But so far I've failed to replicate the behavior of the Ubuntu 
binaries and still hope someone knowledgeable chime in.
