From the developer
WordPress Performance Team's own description of Performance Lab, lightly tidied.
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.
