apache2 compatbility with mpm 

https://serverfault.com/questions/15717/which-apache-package-is-best-for-mod-wsgi-django-application

The worker MPM would be your best choice. It's compatible with mod_wsgi. The event MPM might give higher performance, but is far less often used, and any performance improvement is minimal -- hence I won't recommend it. The worker MPM handles each request in a separate thread, which makes it much more suitable for use on a VPS than the traditional prefork model, which uses a whole process for each connection.
