MITS Profiler

MITS Profiler is a tool by MITS — a WordPress and WooCommerce agency based in Poland. It adds a diagnostic bar to any page by appending ?mits_prof=1 to the URL. It captures timing data from the moment PHP starts and presents it in a dark-themed panel at the bottom of the page — visible only to logged-in administrators.

Tabs included:

• Timeline — absolute and relative timing between WordPress lifecycle hooks (plugins_loaded → init → wp_head → wp_footer)
• Hooks — top 50 slowest action/filter hooks with total time and call count
• Options — most-queried WordPress options + full autoload audit with sizes
• Plugins — loaded PHP file sizes per plugin (proxy for load time)
• Assets — all enqueued scripts and styles, external ones highlighted
• HTTP — outgoing wp_remote_* requests with response time and status
• SQL — all database queries with slow-query highlighting (requires SAVEQUERIES)
• PHP — PHP version, OPcache status and hit rate, memory and execution limits

Key features:

• Zero HTTP loopback — works behind Cloudflare, reverse proxies and strict firewall rules
• No external dependencies or requests
• Admin-only: the panel and all data are never shown to guests
• Export to JSON or CSV for offline analysis
• Works on front-end pages, WooCommerce pages, and WP Admin

SQL query logging requires adding the following to wp-config.php:

define('SAVEQUERIES', true);
