Code Profiler – WordPress Performance Profiling and Debugging Made Easy

Code Profiler – WordPress Performance Profiling and Debugging Made Easy

外掛說明

A profiler to measure the performance of your WordPress plugins and themes.

Code Profiler helps you to measure the performance of your plugins and themes at the PHP level and to quickly find any potential problem in your WordPress installation.

You can profile the frontend and backend of WordPress, a custom URL, or even send a POST payload, custom cookies and HTTP headers to profile a contact form, a checkout process or an AJAX action among many other possibilities.

It generates an extremely detailed and easy to read analysis in the form of charts and tables that shows not only which plugin or theme, but also which PHP script, class, method and function is slowing down your website. It displays many useful additional information such as database queries, file I/O operations and disk I/O usage as well.

It makes it very simple to locate any bottleneck problem in your themes or plugins in order to solve it and speed up your website.
Install, activate it and you can start profiling your site right away.

常見問題集

What are the differences between Code Profiler and services such as Google PageSpeed or GTmetrix?

They are completely different: Code Profiler analyzes the code performance of your plugins and themes on your server, at the PHP level. Google PageSpeed and GTmetrix, instead, analyze the content of a web page from a browser’s perspective.

Do I need to deactivate Code Profiler when I’m not using it ?

There’s no need to deactivate Code Profiler when you don’t use it, it has no performance impact on your site.
Because an update can affect the performance of your site, you should consider running it after every plugin or theme update.

Is Code Profiler multisite compatible?

Code Profiler is multisite compatible. Note however that for security reasons, only the superadmin can run it.

What are the requirements for running Code Profiler?

  • WordPress >=5.0.
  • PHP >=7.1 or 8.x.

What is your Privacy Policy?

Code Profiler does not collect any private data from you or your visitors. It does not use cookies either. Your website can run Code Profiler and be compliant with the General Data Protection Regulation (GDPR) or other similar privacy laws.

This plugin helped me diagnose an optimization issue on my website in few seconds. No optimization efforts were effective. Only when this plugin correctly identified the problematic plugin did the website finally speed up significantly.

It’s hard to believe you get all this for free. I can’t even imagine what the paid version could offer more than the free. Thanks a lot.

I don’t usually leave reviews, but this plugin really deserves it. It let’s you debug in a way Query Monitor doesn’t. I manage to find out lots of bottlenecks on few of my sites. Thank you for providing such a tool, keep it up.

Thanks, bought premium after free version showed a problem with WP Offload Media plugin. Pro version showed much more, glad I purchased.

If you want to see how (without a ton of effort) your theme and plugins are performing, this is the plugin you need to try out. I’m still learning but it’s incredibly helpful to determine if I have any resource hogs on my websites. Highly recommended!

  • By default, the profiler will always abort and throw an error if the server didn’t return a “200 OK” HTTP status code. You can change that behaviour in the “Settings” section if the page you are profiling needs to return a different code (3xx, 4xx or 5xx).
  • WP-CLI: Added support for HTTP basic authentication with the --u and --p parameters. Run wp code-profiler help for more details.

Note that those metrics will be displayed on profiles created with this new version of Code Profiler, not on older profiles. The same metrics can be seen on each profile’s page (click on the tooltip beside the profile’s name) and also when running the profiler from the WP-CLI command line tool.
  • [Pro version] : The “Methods & Functions Performance” section now shows all callers of a function. Clicking on the “View Call” action link opens a new row with the list of callers and, for each one, the full path and line number.
