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.
Cache User Counts on Large Sites
Caches the per-role user counts shown on the Users screen and dashboard for 12 hours, avoiding a heavy query on sites with many users.
Log Pages That Run Too Many Database Queries
Records front-end URLs that run more database queries than a limit you set, with the query count and load time, and lists the worst offenders under Tools > Heavy Pages.
Remove jQuery Migrate on the Front End
Drops the jQuery Migrate compatibility script from public pages. Only use it when your theme and plugins work with current jQuery.
Remove the Months Filter From Admin Lists
Drops the "All dates" dropdown from post and media lists, saving a slow query on sites with many thousands of posts or files.
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.
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.
