Do you want to manage how often the Heartbeat Control API runs on your WordPress site? By default, the Heartbeat API keeps a constant connection between your browser and the server to support real-time features like auto-saving posts, showing notifications, and handling session management. While helpful, this constant activity can put an extra load on your server. Adjusting how often the Heartbeat API runs can help reduce server usage and improve performance without losing essential functionality.
With the Nexter Extension (Free) plugin, you can easily manage how often the Heartbeat Control API runs on your WordPress site.
