This is something I'm coming up with off the top of my head, so I haven't tried it. Somewhere on the page with the information you want to display include an invisible iframe, referencing a php file which pulls information out of your database and throws it into a text file. Your javascript can then, every 10 seconds, both update the information it displays from that text file, and reload the php page within the iframe, thus refreshing the information in the text file for the next load.
In this way you'll only be updating that text file when someone is on the page, but they'll always get updated information. It may be a little sloppy, and could get ugly if you have a bunch of people all looking at the page (and all requesting an update every 10 seconds).
Hopefully it gives you a direction though. :)
