Subject: [webpy] Nginx + WSGI == Blazing Fast!
To: "web.py" <webpy在googlegroups.com>

I know.. I know... Simple benchmarks mean nothing but I couldn't help
playing with the new(ish) mod_wsgi module for my favorite webserver
Nginx.

Nginx: http://nginx.net/
Nginx mod_wsgi module: http://wiki.codemongers.com/NginxNgxWSGIModule

I tested Nginx vs. the recommended setup of Lighttpd/Fastcgi. These
very simple and flawed tests were run on Debian Etch running under
virtualization (Parallels) on my Macbook Pro. Hey I said they were
flawed.. :-)

The results show Nginx/WSGI performing 3x as fast as Lighttpd/Fastcgi,
over 1000 requests per second!!

I tested both with Keep-Alives on and off. I'm not sure why Nginx/WSGI
performed 2x as fast with keep-alives on.
