which would you recommend?
which is faster, reliable?
apache mod_python or nginx/lighttpd FastCGI?
I'm using it with nginx.  not sure if it's really faster, but certainly less RAM/CPU load.  Also it's easier to run several Django processes and have nginx map each URL prefix to a different socket.  still not taking full advantage of nginx's memcached module, but first tests show huge speed advantage.
Running Django with FastCGI or with mod_python
