Is your website losing users because of slow-loading content or glitches like stalled animations or missing photos? The Cloudflare Rocket Loader can help.
When users of your website see big blank boxes with a tiny x in the upper right-hand corner or can’t access key information, they tend to surf to the next site. This means you lose business.
In this complete guide, we’ll dive into Cloudflare Rocket Loader™ all features and capabilities.

What is Cloudflare Rocket Loader?
How Does Cloudflare Rocket Loader Improve Metrics —
Unless your site is completely Java or Ajax based, you can expect to see immediately improved performance metrics when it comes to:
- Time to First Paint (TTFP)
- Time to First Contentful Paint (TTFCP)
- Time to First Meaningful Paint (TTFMP)
- Document Load
This result is a much faster loading time for your users, ensuring they see crucial content such as text and images first.
How Cloudflare Rocket Loader Works
Cloudflare then moves these rewritten rocketscript text files to its content delivery network (CDN), where they are compressed into minified files and defined as smart groups.
How Cloudflare Prioritizes Site Upload
When you enable Cloudflare Rocket Loader, a file called (rocket-loader.min.js) is added to your website.
Cloudflare File Compression
The app also clusters external resources, such as Facebook Scripts and Adsense, and groups them as external files. This allows Cloudflare to serve files to the browser in the order of your site’s HTML document.
Cloudflare and Broken Animations
The only way to resolve this issue is to use CSS animations instead of java.
Cloudflare Breaks Java Slider Animations
The Cloudflare speed app does not work with java slider animations, and your viewer will likely be stuck looking at an icon that says the images are loading, but then they never do. This is due to the strict HTML validation required by our Cloudflare account.
Cloudflare Breaks Xenforo Software
Cloudflare Rocket Loader has a particularly adverse effect on Xenforo, forum software that is Ajax-based. This is because it cannot cancel an earlier rendering of the site’s individual scripts.
CSS Works Best With Cloudflare Rocket Loader
Users of Cloudfare Rocket loader experience a dramatic improvement in load time, as long as you are not Ajax or java-based.
The advice is to change all of your animations to CSS animations, but if you are not willing or able to do this, then the Cloudflare rocket loader may not be the best choice.
Cloudflare Browser Compatibility
Cloudflare rocket’s browser compatibility depends on whether or not you have a Free, Pro, Business, or Enterprise plan.

Disabling Rocket Loader
How to disable Cloudflare Rocket Loader?
If you are running Ads on your site, we recommend keeping the Rocket Loader functionality turned off, as it might conflict with your Ad code and hurts your Ad earnings. This is because the Rocket Loader will load js scripts asynchronously and that hinders any Ad scripts that you’ve put on the page.
These are the steps to disabling Rocket Loader from the Cloudflare dashboard:
1) Go to the Cloudflare Dashboard and search for your website (you can have more than one website in your Cloudflare account).
2) Click on Overview and then look for the sub-menu Speed.
3) Click on Optimization.
4) Scroll down to find the option Rocket Loader to enable or disable it.
To enable the Rocket loader again, perform these steps in reverse.
