The BuddyBoss Performance API is a plugin that provides a performance boost to BuddyBoss-powered websites. It works by caching database queries and reducing the number of database calls required to generate a page, thereby reducing the page load time and improving the overall site performance.

It is designed to be used as a Must-Use (MU) plugin, which means it is loaded automatically by WordPress and cannot be deactivated from the plugin's menu. This ensures that the plugin is always active and working to improve your site's performance.
