Rocket Loader prioritises 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)
- Time to First Contentful Paint (TTFCP)
- Time to First Meaningful Paint (TTFMP)
- Document Load
