Performance Lab

Description

The Performance Lab plugin is a collection of features focused on enhancing 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, Modern Image Formats, No-cache BFCache, Optimization Detective, Performant Translations, Speculative Loading, View Transitions (experimental), and Web Worker Offloading (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.

FAQ

The primary purpose of the Performance Lab plugin is to allow testing of various performance features for which the goal is to eventually land in WordPress core. It is essentially a collection of “feature plugins”, which makes it different from other performance plugins that offer performance features which are not targeted at WordPress core and potentially rely on functionality that would not be feasible to use in WordPress core. The list of available features will regularly change: Existing features may be removed after they have been released in WordPress core, while new features may be added in any release.
