What could be causing my models to be updated so slowly in my multiplayer game?
I'm trying to figure out why it's taking so long for a model in my multiplayer game to update and change positions. Also, as time goes on the model seems to update more quickly, after about 5 minutes or so.

Here's an overview of the mechanics of the game:

     -Javascript file has a "tick" function and within that a php file is called to update the MySQL database with new coordinate information
     -The php file outputs a XML document with the database information
     -Also within the javascript tick function it reads the information from the XML document and uses that information to display a new player model
