can’t speak for wp-rocket or cloudflare and don’t know what of the 3 does what, but based on pagespeed insights there are 4 Opportunities;
1. properly size images -> the image optimization in AO might help, otherwise “shortpixel adaptive images” maybe. or you might want to re-upload and/or resize images to ensure the size they’re shown in is not (a lot) smaller then the uploaded size
2. render-blocking resources: those are 3 JS-files, in case you’re optimizing JS in AO you could try “don’t aggregate but defer” + “also defer inline JS” and remove all exclusions (except if after testing you see some exclusions are needed). WP Rocket & Cloudflare (RocketLoader) both also have options to remove render-blocking JS, but I don’t really know enough about those to guide you ??
3. reduce unused JS; as AO does not know what JS is used and what is not, it cannot help there. it is possible (but I don’t know for sure) that WP Rocket can held by “hiding” some JS until after user interaction
4. defer offscreen images; I think you’re using WP Rocket lazyload, you might be able to tweak settings there, or you can ask their support (they’re great at support)?
hope this helps,
frank
