Better Resource Hints free WordPress plugin

Better Resource Hints will make your WordPress site or application faster and generally more performant by intelligently leveraging resource hints like prefetch, preload, preconnect, and server push. As it stands, WordPress isn’t that bad about providing a base level of these hints. In fact, a basic, dedicated API has been shipped since version 4.6..

Instead of just resolving the DNS, the preconnect hint handles TLS negotiations and TCP handshakes, resulting in reduced page latency. Preloading – Preloading occurs when the browser is told it can start downloading an asset in the background early during page load, instead of waiting until the asset is explicitly called to start the process. This hint is most beneficial for assets loaded later on in the page, but are nonetheless essential to the page’s functionality. More often than not, this is a JavaScript file. Enabling this results in an overall faster load time, and quicker time to interactive. Prefetching – Prefetching assets is similar to preloading, but the assets are downloaded in low priority for the purpose of caching them for later use. For example, if a user hits your home page and is likely to go to a page that uses a heavy JavaScript file, it’s wise to prefetch that asset on the home page, so it’s cached and ready to go on the next. Again, the result is a quicker subsequent page load, quicker time to interactive, and an improved overall
