I don't suppose there's much of a chance that the OP is running Python
on a CPU that doesn't have an integer divide instruction? If that
_were_ the case, the difference would be more noticable, but would
still probably not worth worrying about unless a truely huge number of
operations were being done in a very tight loop with no intervening
I/O operations.
