Backend for web chat?

I need a backend for a web chat feature. I don't have a powerful server to run it on so I'm trying to squeeze as much juice as possible from my 1.5Ghz single core 512MB instance.

At first I thought I would just write a simple polling solution but it turns out there is this thing called comet (reverse-ajax) that in general is more efficient, so I was looking into that and I couldn't find much information.

I'm now thinking of simply installing an IRC server and just writing an AJAX IRC client (although I'm sure there are many other projects too chose from already).

Why does /prog/ think? Am I heading in the right direction?

Personally, I don't see what's wrong with the polling server.

You could also buy grove.io from Leah.

socket.io + whatever socket.io backend for your language of choice

What other language do you expect for a web browser? And then what other websocket/AJAX/Comet/whatever library do you suggest?

We solved the problem over 20 years ago. It's called IRC.

This is a solved problem. There are free web interfaces to IRC. http://kiwiirc.com/docs/development/docs

Would the gentlemen be so kind as to refer me to a nice lightweight IRCd?

inspircd is the only modern codebase. All other ircds are forks of forks of forks of 20-year-old terrible shitty norwegian student code.
Not exactly lightweight, but well... modular.
