Rocket Loader is a general-purpose asynchronous JavaScript optimisation that prioritises rendering your content while loading your site's Javascript asynchronously. Turning on Rocket Loader will immediately improve a web page's rendering time sometimes measured as Time to First Paint (TTFP), and also the window.onload time (assuming there is JavaScript on the page). This can have a positive impact on your Google search ranking. When turned on, Rocket Loader will automatically defer the loading of all Javascript referenced in your HTML, with no configuration required. Refer to Understanding Rocket Loader for more information.
