In 2013 WordPress introduces Heartbeat API – a feature that allows your browser to automatically communicate with the server. However, there are a couple of drawbacks to this feature.

If you use a shared hosting plan, you need to take a closer look at the CPU usage of your server. That’s because some hosting companies might suspend your account when you go over the limit.

Here, we’ll talk why WordPress Heartbeat API is it the usual suspect that causes the issue.

Stop Heartbeat Code


add_action( 'init', 'stop_heartbeat', 1 );
function stop_heartbeat() {


Modify Heartbeat Code

Replace 100 (seconds ) if you need.


function change_frequency_of_heartbeat_settings( $settings ) {
    $settings['interval'] = 100; //Anything between 15-120
    return $settings;
add_filter( 'heartbeat_settings', 'change_frequency_of_heartbeat_settings' );
