MITS Profiler
·
Lightweight WordPress performance profiler. No HTTP loopback requests — works behind Cloudflare and any proxy.
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);
