The problem with this mechanism is that users must wait for the browser to discover and retrieve critical assets until after an HTML document has been downloaded. This delays rendering and increases load times.However the big pitfall of these techniques is that they be cached outside of the page they are embedded in and, if the same code is used in more than one page, we end up with duplicated code in our pages.
