On my computer I tried and lodsd is quite faster.
On my lodsd is the same as mov eax,dword[esi]/add esi,4. However lodsd takes only one byte, so it more friendly to loop unroll.

I'm asking because on my Atom I tested one procedure in two varitants - with lodsb, and with mov al,byte[esi], used QueryPerformanceCounter to measure. The mean value of tests without lodsb was smaller than that with it. Thanks.
