CodeTelemetryLab Admin Performance Inspector
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.
