LiteSpeed Heartbeat Control is a useful feature designed to optimise WordPress site performance. It manages WordPress’ interval heartbeats, which are periodic AJAX requests sent by the WordPress dashboard to the server.
In simpler terms, it’s like setting a timer for how often your WordPress site checks in with the server to ensure everything is running smoothly. This control helps prevent unnecessary strain on the server, leading to a faster and more efficient website.
These heartbeats can sometimes create an excessive server load. By controlling the frequency of these heartbeats, LiteSpeed’s Heartbeat Control effectively reduces server load, ensuring smoother operation and better resource management. However, adjusting these settings requires caution, as inappropriate configurations can disrupt the AJAX-triggered WordPress tasks.
Quick Start Guide
This quick guide provides step-by-step instructions for accessing LiteSpeed’s Heartbeat Control within your WordPress dashboard. This feature allows you to manage the frequency of server requests from your site, aiding in optimising performance and reducing server load.
Steps to Navigate to Heartbeat Control:
- Log in to your WordPress Dashboard: Enter your credentials to access the backend of your WordPress site.
- Access LiteSpeed Cache Settings: On the dashboard, locate and click on ‘LiteSpeed Cache’. This is usually found in the sidebar menu.
- Go to the Toolbox Tab: Within the LiteSpeed Cache settings, navigate to the ‘Toolbox’ tab, which houses various configuration options.
- Find the Heartbeat Tab: Inside the Toolbox, look for the ‘Heartbeat’ tab. Clicking on this tab will reveal the Heartbeat Control settings.
These steps will lead you to the Heartbeat Control feature, where you can adjust settings to optimise your WordPress site’s performance.

Editor Heartbeat Control
- Turn ON/OFF: For the WordPress editor, activate the ‘Editor Heartbeat’ option by setting it to ON.
Setting Heartbeat Time-to-Live (TTL)
Adjusting TTL

In-Depth Guide
Heartbeat Control: A Detailed Overview
Frontend Heartbeat Control: This option, when enabled, allows you to manage the frequency of heartbeats on the WordPress front end. The default TTL (Time-to-Live) is 60 seconds, but it can be adjusted between 15 to 120 seconds based on your site’s needs. Setting it to 0 disables the heartbeat, which might be beneficial for static sites where real-time updates are not critical.
Backend Heartbeat Control: Similar to the front end, this control manages heartbeat frequency in the WP-Admin area. Adjusting this setting helps optimise the load on the server caused by the admin dashboard, particularly on high-traffic sites. The TTL can again be set between 15 to 120 seconds.
Editor Heartbeat Control: This control specifically targets the WordPress editor. By managing the heartbeat frequency in the editor, you can ensure smoother performance, especially when multiple users are editing content simultaneously. The default TTL is 15 seconds, but it can be adjusted for more dynamic or less frequent updates.
Examples and Use Cases
- High Traffic Site: For a website with high traffic, reducing the heartbeat frequency in the backend can significantly reduce server load, enhancing overall performance.
- Content Management: In scenarios where multiple authors are editing content, adjusting the editor heartbeat can provide a balance between real-time updates and server performance.
- Static Content Sites: For websites primarily consisting of static content, disabling the frontend heartbeat can conserve server resources without impacting user experience.
Best Practices and Cautions
- Assess Needs: Before adjusting heartbeat settings, assess your website’s specific needs and traffic patterns.
- Monitor Performance: Regularly monitor your site’s performance after changing heartbeat settings to ensure there are no adverse effects.
- Avoid Extreme Settings: Extremely low heartbeat intervals can increase server load, while very high intervals might delay important updates. Aim for a balanced configuration.
