WordPress插件：Performance Lab

官方简介

The Performance Lab plugin is a collection of modules focused on enhancing performance of your site, most of which should eventually be merged into WordPress core. The plugin allows to individually enable and test the modules to get their benefits before they become available in WordPress core, and to provide feedback to further improve the solutions.

Currently the plugin includes the following performance modules:

• Dominant Color: Adds support to store dominant color for an image and create a placeholder background with that color.
• WebP Support Health Check: Adds a WebP support check in Site Health status.
• WebP Uploads: Creates WebP versions for new JPEG image uploads if supported by the server.
• Fetchpriority: Adds a fetchpriority hint for the primary content image on the page to load faster.
• Enqueued Assets Health Check: Adds a CSS and JS resource check in Site Health status.
• Autoloaded Options Health Check: Adds a check for autoloaded options in Site Health status.
• SQLite Integration: Use an SQLite database instead of MySQL.
