Better webserver performance for Python Django: Apache mod_wsgi or Lighttpd fastcgi
Doesn't answer you question, but do you already use caching for your site? Like memcached? This might give you a better performance gain than going through the mess of switching webservers.
I am currently running a high-traffic python/django website using Apache and mod_wsgi. I'm hoping that there's a faster webserver configuration out there, and I've heard a fair number of recommendations for lighttpd and fastcgi. Is this setup faster than apache+mod_wsgi for serving dynamic django pages (I'm already convinced that lighttpd can server static files better)? The benchmarks online are either poorly conducted or inconclusive so I'm looking for some personal anecdotes. What architectural benefits does lighttpd + fastcgi provide? I understand that lighttpd uses epoll, and that a fastcgi process will be multithreaded. Also, having two separate processes, one for lighttpd and one for the python interpreter, will be largely beneficial.
I am aware of tornado and its ability to handle thousands of file descriptors with much fewer threads using epoll and callbacks. However, I'd prefer to stick with django for now.
Thanks,
Ken
