CodeTelemetryLab Admin Performance Inspector is a developer-focused performance profiling plugin built exclusively for the WordPress admin area. It instruments the WordPress request lifecycle in real time and presents all profiling data inside a clean, dedicated dashboard under Tools Admin Performance Inspector.

No configuration needed. Activate the plugin and instantly see what is slowing down your WordPress backend.

What It Profiles

Admin Page Execution Time
Measures total request time from plugins_loaded to shutdown using microtime(true). Displays the precise execution time in milliseconds on the overview panel.

Plugin Load Performance
Tracks the execution time of every active plugin using a lightweight MU-plugin drop-in. Displays a sortable table of all plugins with their individual load times and flags slow-loading plugins automatically.

Database Query Profiling
Captures every SQL query executed during the admin request using WordPress’s native SAVEQUERIES constant. Displays total query count, slow query count, cumulative query time, and a full query list with origin file and line number. Slow queries (default threshold: 100ms) are visually flagged.

Hook Execution Profiling
Times key WordPress hooks including init, admin_init, admin_menu, current_screen, and wp_loaded. Shows execution time and registered callback count for each hook.

Memory Usage Monitoring
Displays current memory usage, peak memory usage, and percentage of PHP memory limit consumed — with a visual progress bar.

FAQ

Will this plugin slow down my site?

No. The plugin is designed to add less than 5% overhead to the admin page baseline execution time. All profiling is lazy-loaded and only active on admin requests. It has zero impact on your public-facing frontend.

How does plugin load time tracking work?

On activation, the plugin drops a tiny Must-Use (MU) plugin into wp-content/mu-plugins/. This MU plugin times each active plugin as it loads. When you deactivate the plugin, the MU drop-in is automatically removed.

Why do I see a query logging notice?

Database query profiling requires WordPress’s SAVEQUERIES constant to be enabled. The plugin dashboard provides a one-click button to enable it automatically in your wp-config.php. You can also disable it from the same panel when not needed.

Can I change the slow query threshold?

Yes. The default threshold is 100ms. You can adjust it from the plugin settings panel under Tools Admin Performance Inspector.

Is profiling data stored in the database?

No. Version 1.0.0 captures profiling data in memory for the current page request only. Nothing is written to the database. Historical tracking is planned for a future version.

Who can see the profiling dashboard?

Only WordPress administrators with the manage_options capability can access the dashboard. This is enforced on every request.

Does this affect my frontend or public site?

No. The plugin is scoped exclusively to wp-admin requests. No profiling code runs on public-facing pages.

How do I uninstall cleanly?

Deactivate the plugin then click Delete. The uninstall routine automatically removes all plugin options from wp_options and removes the MU drop-in file, leaving your database and filesystem clean.

Is it compatible with WooCommerce and Elementor?

Yes. The plugin has been tested with WooCommerce, Elementor, Yoast SEO, and Contact Form 7. If you encounter any compatibility issue, please open a support thread.
