I think this is the first time I have ever been asked to optimize code without looking at the code! It's hard to optimize pseudo-code. Can you show the real code? I will make some general suggestions. > Does anyone have any suggestions of what I should do? Is Stackless Python > an option? Is there some other steps I could take? Some basic steps? AFAIK Stackless is not faster for single-threaded calculations. Unfortunately heavy-duty number crunching is not a strong point of Python (because every operation requires a virtual method call). Try psyco. Use numpy if you can. Move the calculations into C code (maybe with pyrex). Move loop control into C code by using list comprehension or map. Reduce the number of name lookups. Make names local.
