PHP/JS/JQUERY: Smart method to Auto check/updating a points status

Question

So right now I am using me of this:

function checkpoints()  { 
  var postThis = 'checker.php?userid='+ $('#user_id_points').val();
  $.post(postThis, function(data){
        $(".vispoints").html(data).find(".vispoints1").fadeIn("slow")
  });
  setTimeout(checkpoints, 5000);
}

This function repeats each 5 seconds (sending request each 5 seconds) and running the checker.php each 5 seconds, to show how many points you got. (checker.php echo out how many points you've got in a span class vispoints1).

Now isnt there a smarter method doing this, instead of sending requests like this all the time.. I mean sites like facebook and that, they dont do like this to check if you e.g got a new friend request?

Hope you can help me find a better method examples would be good too.

Actually, sites like Facebook do employ polling to get certain notifications. If you're using Firefox, install the Live HTTP Headers plugin and you'll see timed calls to facebook servers.

For your app, polling every 5 seconds is far too much. Scale it back to every couple of minutes. Anything that requires that much "granularity" shouldn't be using javascript but rather a different language that can open a port on the server.

So i should continue using my function but just instead of 5 seconds have it to 1-2 minutes? I thought it was possible that exactly when you earn points you'll see your new points increase
