First let me say that I really like Nevow template system. Once you became expert with it, it proves to be really flexible.
The problem is the performance. I have done a simple test with the rendering of a table 5 * 20, Nevow against Django, and Nevow is much slower.
The problem is that, I think, there are a lot of objects adaptation.
How confident are you about that? When I was last playing this game, it seemed to be copying lots and lots of stuff that was the main source of the slowdown, and I got a factor of 2 speedup by dint of a hack: http://codespeak.net/svn/user/mwh/pydoctor/trunk/pydoctor/nevowhtml/__init__...
Is it possible to use that same model used by django.template?
You pass a context (that is a dictionary usable like a stack: push/pop) to the render function. All the data directive will search the data in the context (like djando, first dictionary lookup, then attribute lookup, and so).
As an example n:data='x.y' ==> ctx['x']['y']. A rend.Page.renderHTTP can build a context from the instance dictionary.
I'm not sure I understand. You can implement IResource.renderHTTP however you like, I guess...
