You might have a look at node.js - I've heard recently of apps which combine node.js w/ redis pubsub to get a pretty nifty quick experience w/ no polling. From a scalability and performance point of view, this has a couple of drawbacks - susceptible to network latencies, quality (may be better suited for intranet), and second, each client may need it's own port (this for node.js).
Here's a pretty cool little app - http://www.web2media.net/laktek/2010/05/25/real-time-collaborative-editing-with-websockets-node-js-redis/

Hi,
I am developping a little chat application with rails. On my chat page I
make ajax request every 10 seconds to check if there are news messages.
I think if I keep this thing with a lot of user my performance will get
really low.
How can I improve this? Is is possible to observe when a row is added?
Or how can I effeciently cache the messages?
Thanks,
Greg
