It was not supposed to change speed (directly). Rather, it was supposed to reduce code size, which would let us do more interleaving and unrolling, and may help us achieve greater speed (later) in this way. You may check the compiled code before/after this change with "size" and "objdump -d". Did some instructions change from 32 to 16 bits? Alexander
