It is about two orders of magnitude and it looks like your Maple code
is actually compiled. In case I am reading your code right could you
tell us what the runtime of an interpreted version of your code would
be like? I would guess that with Cython one could get similar timings,
but overall this is not relevant to the slowdown observed ;)
