Essentially, there are two parts to this website - Django and PHP which are proxied through FCGI using flup and php5-cgi respectively. Easy peasy! :-) Memory utilisation wise, 4 worker processes + 4 php5-cgi + 4 flups use about the same as Apache on WSGI and PHP. So far it seems to me that the page response time is lower on Nginx (inference based solely on ad-hoc web browser load time rather than any specific benchmark). Images and any static resources do load faster on Nginx.
