Flying Pages vs Performance Lab

Flying Pages preload pages before the user click on it, making them load instantly How it Works? Flying Pages injects a tiny JavaScript code (1KB gzipped), waits until the browser becomes idle. Then it detects pages in the viewport and on mouse hover and preloads them. Flying Pages is intelligent to make sure preloading doesn’t crash your server or make it slow. Preload pages in the viewport – Detect links within the viewport (current viewing area) using ‘Intersection Observer’ and tells the browser to preload them using ‘prefetch’, switch to xhr if not available (similar to Quicklink). Preload pages on mouse hover – On hovering links, if it’s not preloaded yet using above ‘viewport’, then Flying Pages will prefetch them instantly (similar to Instant.page). Limits the number of preloads per second – If your page has too many links, prefetching all at the same time will cause the server to crash or slow down the website to visitors. Flying Pages limits the number of preloads per second (3 req/sec by default) using an in-built queue. For example, if you’ve 10 links in the viewport, preloading all these are span into 4 seconds. Stops preloading if the server is busy – In case the server starts to respond slowly or return errors, preloading will be stopped to reduce the server load. Understands user’s connection and preferences – Checks if the user is on a slow connection like 2G or has enabled data-saver. Flying Pages won’t preload anything in this case.

The Performance Lab plugin is a collection of features focused on enhancing the performance of your site, most of which should eventually be merged into WordPress core. The plugin facilitates the discovery and activation of the individual performance feature plugins which the performance team is developing. In this way you can test the features to get their benefits before they become available in WordPress core. You can also play an important role by providing feedback to further improve the solutions. The feature plugins which are currently featured by this plugin are: Embed Optimizer Enhanced Responsive Images Image Placeholders Image Prioritizer Instant Back/Forward Modern Image Formats Optimization Detective (dependency for Embed Optimizer and Image Prioritizer) Performant Translations Speculative Loading View Transitions (experimental) These plugins can also be installed separately from installing Performance Lab, but having the Performance Lab plugin also active will ensure you find out about new performance features as they are developed.
