No, I didn't publish the results (I know, shame on me) and the only thing
left now is text file with *some* results (ironically, results for
nginx+mod_scgi are missing).

Anyway, it looks like the test was "search for the best way to run WSGI
applications".

The application in question was simple "Hello World!" backed by Google's
webapp framework.

I tested Apache, Cherokee, lighttpd and nginx. Each server was tested (when
possible) with FastCGI-to-WSGI, SCGI-to-WSGI and WSGI. Proxy was tested
using CherryPy and Paste.

Some random thoughts:
1) I didn't like Cherokee and lighttpd,
2) SCGI seems to be ~20% faster than FastCGI (but this is probably because
of small response size in test app),
3) CherryPy behind nginx beats every other web server (req/s) and only
losses to standalone CherryPy (and I'm not comfortable enough to run it
without "real" web server in front of it). At least it did at the time, now
it probably looses also to Tornado behind nginx ;)

Proxy has also two very strong advantages over any Gateway Interface:
1) it's language & framework agnostic, and even if your framework can't talk
HTTP you can always run Python apps using CherryPy's web server, Ruby apps
using Thin and PHP apps behind Apache (because it's the only environment
those broken apps works in),
2) there are no issues with pushing traffic over TCP/IP to other machines
(think: clusters / web farms).

Also, this test was the reason why I started using nginx ;)
