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.
Preload a Chosen Hero Image per Page
Adds a "Preload hero image" field to the post and page editor; when filled in with an image URL, that image is preloaded with high priority on that page, improving Largest Contentful Paint for pages whose main image is not the featured image.
Preload the Site Logo
Preloads the logo set in the theme or Site Editor so it appears with the first paint of the header.
Speed Up the Custom Fields Meta Box
Skips the slow database query that fills the Custom Fields key dropdown, which can freeze the classic editor on sites with lots of post meta.
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.
