Test the performance with a lot of items. The Timeline can load hundreds of thousands of items, but the performance of rendering them in the browser is limited. Rendering typically runs smooth for up to a few hundreds of items at once (you can set a <code>zoomMax</code> to prevent the user from zooming out too far).
