Whenever any CDN, including Cloudflare, has to fetch from the origin server, it's going to be slower.

When a browser fetches images, css and javascript, those resources are usually static (the same for every person browsing the site). So the odds are high they will be cached, and that assets from page-load will be faster.

Same thing with HTML pages that don't change much such as a site's front page, articles, etc. Threads, however, can not only change often, but depending on whether the user is logged in (and their user permissions as well), or a guest, the page may or may not be cacheable by the CDN.
