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.
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.
Fast 404 for Missing Images, Scripts and Styles
Answers requests for missing images, CSS, JavaScript and font files with a tiny 404 instead of loading a full theme page, saving server time.
Keep Speculative Loading Away From Cart, Checkout and Account Pages
Tells WordPress's built-in speculative loading (prefetching pages on hover) to skip cart, checkout and account pages, which are personal, never cached and expensive to build, so hovering over their links no longer costs server time.
Log Slow Outgoing HTTP Requests
Times every request your site makes to other servers (update checks, APIs, license servers) and records the ones slower than a second under Tools > Slow HTTP Calls, so you can find what is holding up page loads.
Run WP-Cron From a Real Cron Job
Stops WordPress from checking for scheduled tasks on every page view; you trigger wp-cron.php from your server's cron instead, which is faster and more reliable.
Send Emails in the Background
Queues emails sent by WordPress and plugins and sends them a few seconds later through WP-Cron, so form submissions, orders and registrations no longer wait for the mail server.
Server-Timing Header for Administrators
Adds a Server-Timing header with PHP time, database query count and peak memory to pages viewed by administrators, so you can read the numbers in your browser's developer tools Network tab.
Stop Elementor From Loading Google Fonts
Prevents Elementor from requesting fonts from Google's servers, for faster pages and fewer third-party connections.
