What is the WordPress Performance Lab plugin?
Finally, a performance-related feature from WordPress!
Having an official plugin directed at increasing the performance of WordPress and new functionalities is a good sign that WordPress is being taken more seriously. This will definitely help the WordPress community to improve and even out the performance of websites.
What is the WordPress Performance Lab plugin?
The WordPress Performance Lab plugin is a collection of modules focused on enhancing the performance of your site, most of which should eventually be merged into WordPress core. The plugin allows you to test the modules to get their benefits before they become available in WordPress core and to provide feedback to further improve the solutions.

How it works
The plugin is fairly simple to use but does require some setup. Enabled modules are not active until you activate them in the Performance Lab menu, and each module can be enabled and disabled independently.
WordPress Performance Lab features:
Enable WebP Uploads
Creates WebP versions for new JPEG image uploads if supported by the server.
Enable Audit Enqueued Assets (experimental)
Adds a CSS and JS resource check-in Site Health status.
Enable WebP Support
Adds a WebP support check-in Site Health status.
Enable Persistent Object Cache Health Check
Adds a persistent object cache check for sites with non-trivial amounts of data in the Site Health status
