[Chicago] web server benchmarks

[Massimo Di Pierro]

This is to let you know that web2py is considering moving away from  
cherry wsgiserver and use the rocket web server created by Timothy  
Farrell.

Rocket is posted here http://launchpad.net/rocket

Here are the motivation why we think Rocket is the best Python web  
server available:

- It is faster then cherrypy and can handle more concurrent  
connections. Here are the benchmarks
http://groups.google.com/group/web2py/attach/a04d593fb423f76f/Rocket+Benchmarks.pdf?part=2&view=1
- It is a multi-treaded server
- It runs everywhere (Tornado requires epoll for example)
- It runs with Python 2.x, 3.x and Jython.
- The source code is very easy to read compared for example with  
CherryPy.
- For HTTPS it only requires the ssl module that comes with >=2.6  
while Cherrypy does also require OpenSSL
- CheeryPy seems to truncate large files over HTTPS. We tested rocket  
in upload and download for up to 2GB files without issues.

We are still testing it. If you try it and encounter any problem  
please let me know. If you have any independent benchmark also please  
let me know.
