Correct me if I'm wrong, but at a high level you appear to basically just have a mapping of strings to values and you are then shifting all of those values by a fixed constant (in this case, `z = 5`). Why are you using a dict at all? It would be better to use something like a numpy array or a

Re: multiprocessing shows no benefit

Could you post a full code snippet? If the lists of 16k numpy arrays are fixed (say you read them from a file), you could just generate random values that could be fed into the code as your list would. It's hard to say how things could be sped up without a bit more specificity. Cheers, Thomas --
