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?
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).

It shouldn't if you structure your queries efficiently

Perhaps, but pushing to the browser is difficult or impossible.
Or how can I effeciently cache the messages?
Thanks,

You're doing premature optimization. Worry about the bottlenecks when
you can actually measure them, not when you're just speculating.
