Snippet Library
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.
Add ?wpide_queries=1 to any page while logged in as an administrator to see, at the bottom of the page, the queries that ran more than once and the ten slowest queries, with the code that called them.
Counts admin-ajax.php requests per action (and whether they come from the front end or the dashboard) for the current day and the previous six, and shows the busiest ones under Tools > AJAX Usage.
Measures how long each scheduled task (cron event) takes to run and records the slow ones under Tools > Slow Cron Tasks, so you can spot the plugin that makes WP-Cron sluggish.
Shows an admin bar item on the front of the site with the total size of the page's scripts, stylesheets, images and fonts, and a breakdown with the heaviest files when you click it.
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.
