Speaking of MMX, i remember reading that someone rewrote their idea
algorithm to take advantage of MMX (changed nothing else but that, so no
other real optimizations were added), and the throughput of their crypter
in ECB mode (only one they were using in the program) went from under
10mbps to 45mbps (5,735 k i think was their figure).
