Hi Eugenio,

Thanks for letting me know. I agree, if WP Rocket is giving you the best results, it’s best to stick with that.

To be honest, making the assets CDN fully compatible with WP Rocket is basically impossible. StaticDelivr is a CDN for open-source assets, so it serves original files straight from the ww.wp.xz.cn repository. WP Rocket works by changing and combining those files into unique versions on your server. Since the files aren’t originals anymore, the CDN can’t find them to serve them.

It would be cool to see if LiteSpeed actually feels faster for users in different cities globally though. Sometimes a global CDN setup performs better in the real world for distant users, even if local speed scores look similar.

Thanks again for all the help testing these things out! I’m glad the images are working well now.

Best regards.

Hi Eugenio,

Were you having problems with the assets CDN by any chance – especially with Premium plugins or themes?

Thank you.

Hi, thanks for the question.

The plugin does not use lazy loading or preloading. All images are standard <img> tags, so the browser loads them normally and concurrently. Because the CDN delivers each image very quickly, usually around 50 ms, there is no performance benefit from adding lazy loading or preload.

Lazy loading would actually make things slower. When you scroll, the browser waits until the image enters the viewport before requesting it. If the image is not cached yet, the first request takes around 400 to 500 ms to process, which creates a noticeable white flash while scrolling. With normal loading, all images are already requested at page load, so everything is ready when you reach it.

Preloading is also not helpful. Forcing the browser to preload images adds extra work during the initial HTML rendering, which can delay the first paint and slow down the start of the page. Since the CDN already loads images extremely quickly and the browser handles them concurrently, preloading does not provide any real benefit.

Let me know what you think.

Hi Eugenio, it should be all working for all new images and gifs.

Thanks for the great review! Really happy to hear it helped you hit 97 on mobile PageSpeed.
I’m glad I could help with the support questions, and I really appreciate you taking the time to write this. It helps a lot!

Thats all good. Do you want to try setting format to AVIF and WebP on two seperate test in your PageSpeed Insights and see if AVIF is faster? I may be wrong.

Hi Eugenio,

Thanks so much for confirming. I’m really glad everything is working smoothly now.

I really appreciate your patience and the detailed reports along the way, they helped improve the plugin for everyone. And as mentioned earlier, feel free to reach out to me personally anytime if you need help with anything at all.

Cheers 🙂
