> If you use the default repo on Lucid (as suggested by the author), you will end up with a very old version of Nginx that doesn't even natively support wsgi.
Nginx+Gunicorn combination uses HTTP, so WSGI support is not needed in that case.
uWSGI supports HTTP and FastCGI too, natively. Using the uwsgi protocol (that has nothing to do with WSGI standard) is only a way to increase performance and add a bunch of features. uWSGI and gunicorn are very different projects, with very, very different targets. Trying to make a fair comparison is impossibile.
