How to Disable Unused Scripts, Emojis, and Heartbeat in WordPress
By default, WordPress injects dozens of legacy scripts and inline styles into your website header that modern business websites simply do not need.
1. Disable Native WP Emojis
Every modern smartphone and desktop OS has built-in emoji font support. Disabling WordPress's legacy emoji script removes an unnecessary external HTTP request.
2. Throttle the Heartbeat API
The WordPress admin Heartbeat API continuously polls the server every 15 seconds, driving high CPU consumption on shared hosts. Throttling interval frequency to 60 seconds saves server compute.
