In various example embodiments, heavy document object model (DOM) elements in a heavy web page are removed directly from a DOM tree subsequent to a request being received to navigate to another web page but before the web browser actually navigates to that other web page. In one example embodiment, the heavy DOM elements are deleted from the previous page during an ‘onbeforeunload’ event using a scripting language such as Javascript, to ensure that the render of the next page starts faster.
