I was going through Python posts and this post caught my attention http://groups.google.com/group/comp.lang.python/browse_thread/thread/f99326a4e5d394e/14cd708956bd1c1a#14cd708956bd1c1a
<quote> You have missed an important point. A well designed application does neither create so many threads nor processes. The creation of a thread or forking of a process is an expensive operation. You should use a pool of threads or processes. </unquote> I am creating an application and it creates ~1-2 threads every second and kill it within 10 seconds. After reading this I am worried. Is creating a thread a very costly operation? I cannot use a pool of threads because I am using an external application (twisted) to create the threads (deferToThread). -- http://mail.python.org/mailman/listinfo/python-list
