[Twisted-web] performance of web2

I have begin to play with twisted.web2.

The first thing I have done is a comparative test against Nevow.

The Nevow code:
class Main(object):

     def renderHTTP(self, ctx):
         data = "hello world" * 1024
         return data
     def locateChild(self, ctx, segments):
         return self, ()

and twisted.web2 code:
class Main(object):
     def renderHTTP(self, req):
         data = "hello world" * 1024
         return http.Response(stream=data)

     def locateChild(self, request, segments):
         return self, server.StopTraversal

I have used ab2 from apache2.
With n = 100 and c = 1:
- nevow: 1062 req/sec
- web2:  980 req/sec

With n = 500 and c = 50
- nevow: 1231 req/sec
- web2:  1101 req/sec

(plain twisted.web is a bit faster: 1323 req/seq and 1793 req/seq)

This is not a problem (and maybe the tests are not so accurate), but I 
would like to known if there are still some areas that can be optimized 
in twisted.web2 or the development is stable.

Thanks and regards  Manlio Perillo
