That doesn't seem to follow from your original post. Because Numpy is a C extension, its performance would not be improved by psyco at all. The 20% performance increase that you reported must have been a result of the JIT compiling of some Python code, and if you can identify that and rewrite it in C, then you may be able to see the same sort of boost you had from psyco. -- http://mail.python.org/mailman/listinfo/python-list
