Where does a WordPress request spend its time?

Code Profiler Pro examines PHP activity on your server as WordPress handles frontend and backend requests. Its charts and tables show performance by add-on and theme, then help you narrow a bottleneck to the PHP script, class, method, or function involved. This view focuses on server-side code; browser-based page speed utilities measure rendered pages from a visitor’s perspective.

Which code and activity can you inspect?

Pro profiles PHP scripts, methods, and functions, and reports database query performance and remote connections. You can also review file I/O operations and statistics, disk I/O usage, and filter results to focus on the relevant activity.

• Compare performance across WordPress add-ons and themes.
• Trace timing to scripts, classes, methods, and functions.
• Review database queries and remote connections.
• Inspect file and disk I/O activity.

Can you profile a complete process?

Choose frontend or backend requests, cron events, or a custom URL. GET and POST methods, custom cookies, and HTTP headers let you set request conditions for workflows such as contact form submissions, checkout processes, and AJAX actions.

Profiling can also help with update reviews: execute a profile after a plugin or theme update and compare the results with earlier findings. Charts can be exported as PNG pictures; Pro also exports tables and charts as CSV. WP-CLI integration provides another way to run the profiler.

What does setup and access involve?

Install and activate Code Profiler Pro in WordPress, then open the Code Profiler menu and choose the area or workflow to examine. The stated requirements are WordPress 5.0 or later and PHP 7.1 or 8.x. It supports multisite installations, where only the superadmin can run it for security reasons.

The product information states that Code Profiler does not collect private data from you or your visitors and does not use cookies. It can remain active when you are not profiling; the product information says it has no performance impact on the site when unused.
