Controls the WordPress Heartbeat API — the polling mechanism WordPress uses to keep admin sessions alive, handle autosave, and support post locking. By default it fires every 15–60 seconds per logged-in browser tab, creating a steady stream of admin-ajax.php requests that can stress the server on busy sites. This plugin lets you throttle the interval or disable it entirely on a per-screen basis.
