> Is it the > x64 working faster at its design sizes Another guess (still from the darkness of not having received the slightest clue what the test actually does): if it creates integers in range(2**32, 2**64), then they fit into a Python int on AMD64-Linux, but require a Python long on 32-bit Windows; long operations are much slower than int operations.
