Hi, I currently use Twisted Web as a WSGI container for my Flask application. I'm trying to get good concurrent user requests but running into some hiccups.

I see that for each user session that hits my server, twistd creates an OS thread. This of course will not scale will with concurrent users.

This behavior is defined by the WSGI specification. If you don't want this behavior, you don't want WSGI. Perhaps you want to write a native Twisted application, perhaps using klein. Or you could find one of the WSGI variations that aims to support asynchronous operation instead of multithreaded operation (but Twisted doesn't provide a container for any of those). Jean-Paul

Is there a better way or perhaps command parameter I can use to support concurrent users with something like non-blocking IO which can handle thousands of concurrent users.

thanks! Darren
