Change the Autosave Interval
Autosaves drafts every two minutes instead of every minute, in both the block editor and the classic editor.
Snippet Library
Performance snippets for WordPress
Snippets that make WordPress lighter and faster: remove emoji scripts and embeds, control the Heartbeat API, limit revisions and load scripts only where they are needed. For developers and site owners chasing better Core Web Vitals.
Disable the Heartbeat API Except in the Post Editor
Keeps the Heartbeat API (autosave and post locking) in the editor but turns it off on every other admin and front-end page to save server requests.
Turn Off Autosave for Chosen Post Types
Stops the editor from autosaving the post types you list (for example products or custom data types edited by many people), which removes frequent background requests and extra autosave revisions.
