What does the Rocket Loader do?
Rocket Loader priorities your website’s content (text, images, fonts etc) by deferring the loading of all of your JavaScript until after rendering.
On pages with JavaScript, this results in a much faster loading experience for your users and improves the following performance metrics:
- Time to First Paint (TTFP)
- Contentful Paint (TTFCP)
- Meaningful Paint (TTFMP)
- Document Load
