I managed to 1/3 the memory requirement of our program by using __slots__ on the most common class (several hundred thousand instances!). When doing these optimisations I ran a repeatable script and measured the total memory usage using the OS tools (top in my case). -- Nick Craig-Wood <n...@craig-wood.com> -- http://www.craig-wood.com/nick -- http://mail.python.org/mailman/listinfo/python-list
