It almost doubles the speed, of course, if it's an odd
number of bytes, you need one additional STOSB before
(or after, depending if the initial address was even or
odd). I'm getting courious about the optimizations your
compiler does. I loved the string operations, since
they are the closest stuff to caracter operations on a
mainframe, and I know most compilers had a real problem
using them.
