I did my research on how to implement comet like chat on asp.net / MVC.
what i found was it can be done by Long Polling..

about long polling , because it keeps the threads open so many concurrent connections will be made making its porformance poor (or flat zero), cuz IIS aint meant for many concurrent connections

Now the Tools For Business :Pokein, SignalR, SocketIO, Now.Js (Skipping paid tools, Free is pretty 🙂 )
as far as i know all these use long polling ,then what do they actually du to improve performance in IIS (All these can be used with asp.net)..

I also found Facebook uses Erlang (Dunno how to use it) to make it happen & ofcourse $100 million worth of hardware(balancing 70 million user). and FB uses long polling not some comet server( as far as my research goes).

I want to implement scalable long polling on asp.net MVC 3
the two finalsit i found are Here and here

All i want to know which is better and why..
and also which tool is best among the given ones

    My opinion would be that SignalR would be the better choice, if not only because if you use SignalR.WebSockets, it will automatically upgrade the connection to web sockets if the user’s browser supports it. This way, over time, as users begin to upgrade the browsers and away from the long-polling scheme, the scalability of your chat application will actually get better.

    Moreover, there is an awesome code example called JabbR, created by the very people that created SignalR. (who also happen to be developers on the ASP .NET team)

    http://jabbr.net/ – an example of SignalR in action.
