Yup, I was going to suggest the same thing.
Problem is, you're into a minimum of four instructions to set up the 
pointers, then one instr per byte.  For speed, straightline the code and 
don't use a loop. Don't forget the time you spend setting up the loop, and 
checking if you're done every time, is significant in a short loop.
