Two things to try, in order: 1) Can you optimize your algorithms? Three days of processing is... a LOT. 2) Rewrite some key portions in C, possibly using Cython (as MRAB suggested). You may well find that you don't actually need to make any language-level changes. If there's some critical mathematical function that already exists in C, making use of it might make all the difference you need. ChrisA -- http://mail.python.org/mailman/listinfo/python-list
