Extend onenterframe timer?

I'm trying to find out if there is a way to make the html page refresh less often. From what I think is the page looping through all the objects and calling the onenterframe function of these objects. Is it possible to slow this process down so it does the loop less often?

I could be totally of on the way it functions but if Im somewhat on track Im hoping this will increase the performance of our page since it's been taking up a lot of resources.
