Wouldn't diff be faster because it doesn't have to read to the end of every file and it isn't really calculating anything? Or am I looking at this in the wrong way.

If the files are the same (which is what the OP is hoping), then diff does indeed have to read to the end of both files to be certain of this. Only if they differ can it stop reading the files as soon as a difference between them is found.
