WSGI is a generic interface which allows a Python web application to be hosted on different hosting mechanisms. The mod_wsgi module for Apache is purpose built for it. With how you are running Django now you are relying on a mod_python specific binding for Django rather than the generic WSGI interface that Django also supports. By going the mod_python route you are encumbering yourself with greater memory usage as mod_python is loading a lot of stuff you don't need for hosting Django. The raw performance of mod_python is also not as good as mod_wsgi. The mod_wsgi module also has daemon mode, which allows separation from Apache child processes for your application, giving more predictable performance if you haven't been bothered to customise default Apache MPM settings, which aren't suitable for large Python web applications. For some real data see: http://collingrady.wordpress.com/2009/01/06/mod_python-versus-mod_wsgi/ http://code.google.com/p/modwsgi/wiki/PerformanceEstimates Go onto #django irc and you will very much find that mod_python is out of favour these days, despite what official Django documentation still says about it.
