详情介绍:
MITS Profiler 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
- 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
wp-config.php:
define('SAVEQUERIES', true);

常见问题:
Does this plugin slow down my site for visitors?
No. The profiler only activates when ?mits_prof=1 is present in the URL, and even then it only renders its output for logged-in administrators. Regular visitors are completely unaffected.
Does it work behind Cloudflare?
Yes. Unlike profilers that rely on HTTP loopback requests (which Cloudflare blocks), MITS Profiler measures time inline within the same PHP process — no outgoing requests needed.
How do I see database queries?
Add define('SAVEQUERIES', true); to your wp-config.php before the line /* That's all, stop editing! */. Remember to remove it when done, as it adds overhead on every page load.
The panel does not appear
Make sure you are logged in as an administrator and that the URL contains ?mits_prof=1 (or &mits_prof=1 if the URL already has a query string).
