I'm not an expert at all, but I far as I understand if you cannot 
vectorize your problem, numpy is not the best tool to use if the speed 
matter a bit.

Of course it's not a realistic example, but a simple loop computing a 
cosine is 3-4 time slower using numpy cos than python math cos (which is 
already slower than IDL).
