WordPress: Heartbeat Control

What is Heartbeat?

The Heartbeat API included in WordPress version 3.6 and later is designed to provide fluid updates between your browser and the server to allow autosaving, post locking, login expiration warnings, and much more. It works in the background to send a regular "pulse" between the browser and the server that is repeated at regular intervals and can be used to keep them in sync.

However, the downside of Heartbeat is that it can cause high CPU usage on the server. (In fact, even if you were to simply login to your WordPress Dashboard and minimize your browser while you worked on other tasks, the API would by default still be updated at regular intervals in the background.)

If you have experienced heavy CPU loads and are using a version of WordPress with Heartbeat included, you can follow the steps below to disable or manage the WordPress Heartbeat API to reduce your server load.
