I am trying to implement a Comet style (e.g. chat) application using IronPython. While I don t need to scale to twitter like dimensions, it is vital that the response time is lightening fast. All the possibilities in Python (Twisted, Tornado, Magnum-Py) do not work with IronPython, often because of epoll support.
Is there a default choice in the .Net world for comet style applications? Or a pure python implementation with long-pulling support? I have tried NTornado, but performance is currently very poor (100-1000x slower than Tornado).
