So That means blindly using threads on any process won't help! >probably have to look at multiple processes rather than > multiple threads. How do I do that??? Does that mean forking the processes or does that mean to change the entire architecture to do small tasks in different processes??? >Alternatively you could move parts of the processing out > of the Python environment by rewriting inner loops in C Any reference/documentation for that???
