<h4>A profiler to measure the performance of your WordPress plugins and themes.</h4>
<p>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.</p>
<p>You can profile the frontend and backend of WordPress, as well a cron events, a custom URL, 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.</p>
<p>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.</p>
<p>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.<br />
Install, activate it and you can start profiling your site right away.</p>

Code Profiler – WordPress Performance Profiling and Debugging Made Easy

Kudos to this amazing plugin. This was a dream, and now it's real!

The dream of many developer is now real


I am a developer of premium plugins, and I was able to discover a real bottleneck in our own plugin with this profiling tool. I use the PRO version for this, worth any money, and the breakdown by script file / method / execution time is great!



I don't know what magic is behind this (probably the calculation based on the backtrace), but it's awesome and doesn't require another PHP extension.


This is truly amazing!


This plugin is not much good without the pro upgrade. Seems unfair that I need to buy an annual subscription so I can run this plugin once or twice to fix issues and then never use it again. I understand the product  needs to be maintained but the fee is way too high for a single use. 


Pro is too expensive


This worked surprisingly well! Very useful settings. Much better than the old P3 profiler.  


Worked surprisingly well


I love Code Profiler, with it I can figure out which plugins have a poor performance and I can think about if this plugin is really that important to have or if I can just throw it out.



After having a specific problem with my site I posted a feature request in the forum, they were working on it quickly and the support was very good! I bought the premium version and I am impressed. I could lower the loading speed of some of my sites by 50-70% because Code Profiler helped me identify the problems.


I love it sooo much


Having looked at the screenshots before installing this plugin, I was dismayed to find that most of them refer to the premium version. 



I don't think it's acceptable that the screenshots attached to the free version of the plugin should be for the paid-for pro version - this is false advertising in my eyes. 


Deceptive advertising practices


Great support that goes far beyond supporting the plugin itself 🙏😊


Great support


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


Excelent


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.


Perfect

Very nice plugin and coded well!

So good

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

Perfbase

<p>Perfbase profiles WordPress applications and sends performance traces to the Perfbase APM platform. It captures request lifecycle timing, WordPress context, selected metadata, and trace data through the native Perfbase PHP extension and the shared Perfbase PHP SDK.</p>
<p>This plugin is a Software-as-a-Service integration. It requires a Perfbase account, a Perfbase API key, and the native <code>ext-perfbase</code> PHP extension. The plugin does not submit traces until profiling is enabled and an API key is configured.</p>
<p>The plugin can profile:</p>
<ul>
<li>Standard HTTP requests.</li>
<li>Admin requests when enabled.</li>
<li>AJAX requests.</li>
<li>WordPress cron runs.</li>
<li>WP-CLI commands when enabled.</li>
<li>WordPress, theme, plugin, REST, and WooCommerce context when available.</li>
</ul>
<p>For privacy and cardinality control, request URLs are stored without query strings. Important WordPress query parameters are stored separately where useful.</p>
<h3>External Services</h3>
<p>This plugin connects to the Perfbase APM platform, an external application performance monitoring service, when profiling is enabled.</p>
<p>Service name: Perfbase APM platform and the configured Perfbase ingest API endpoint. The default endpoint is <code>https://ingress.perfbase.cloud</code>.</p>
<p>Service policies: <a href="https://perfbase.com/privacy/" rel="nofollow ugc">Perfbase Privacy Policy</a> and <a href="https://perfbase.com/terms/" rel="nofollow ugc">Perfbase Terms</a>.</p>
<p>When data is sent: trace data is sent only after a Perfbase API key is configured, profiling is enabled, the request passes the configured sampling rate, include/exclude filters, user-agent exclusions, request-type toggles, and HTTP status-code rules. For HTTP, AJAX, cron, and WP-CLI lifecycles, submission normally happens at the end of the lifecycle or during shutdown. The plugin does not submit profiling traces while profiling is disabled or while no API key is configured.</p>
<p>Perfbase can send:</p>
<ul>
<li>Native trace payloads: function call trees, function names, source file paths and line numbers, timing, CPU, memory, host resource metrics, call context, and runtime error or exception context.</li>
<li>System/resource data: host operating system, kernel, hostname, CPU architecture, CPU details, disk capacity details, memory usage, CPU usage, disk I/O, and network I/O samples.</li>
<li>Process-list tracking when enabled: capped process snapshots with process ID, executable basename, OS user, CPU usage, memory usage, and process runtime. Command-line arguments are not included in process snapshots.</li>
<li>Additional native trace metadata: normalized SQL query text and query type, database DSN/host/database/username/port metadata, MongoDB or Elasticsearch query/filter payload summaries, Redis or Memcached keys and fields, HTTP URL or URI metadata that may include query strings depending on the PHP API or HTTP library used, HTTP method/status/timing/byte-count metadata, file paths and file operation metadata, mail recipient and subject metadata, shell/process command strings, AWS operation names, OPcache and JIT statistics, PHP error or exception samples, compiled file paths, magic method counts, and truncated function argument values if argument capture is separately configured.</li>
<li>WordPress request metadata: action name, HTTP method, request URL without query string, HTTP status code, user IP address, user agent, logged-in user ID when available, hostname, environment, application version, PHP version, WordPress version, and Perfbase plugin version.</li>
<li>WordPress context metadata: AJAX action, REST route, admin page, post/page identifiers, post type/status, taxonomy context, template and theme information, conditional page type flags, plugin lifecycle context, and WooCommerce page, cart, product, or order context when available.</li>
<li>Operational summaries: memory usage, database query count and timing summaries when available, and sanitized outbound HTTP request metadata when HTTP tracking is enabled.</li>
</ul>
<p>Perfbase does not collect:</p>
<ul>
<li>Source code.</li>
<li>Request bodies, full POST payloads (<code>$_POST</code>), arbitrary form fields, or uploaded file contents.</li>
<li>Cookie values (<code>$_COOKIE</code>) or PHP session data (<code>$_SESSION</code>).</li>
<li>Authorization header values.</li>
<li>Passwords, API keys, nonces, or session IDs from WordPress request, cookie, or session data.</li>
<li>Command-line arguments for process-list snapshots.</li>
</ul>
<p>Feature flags control the extra native trace metadata listed under “Perfbase can send”, including outbound HTTP URLs or URIs with query strings for some HTTP libraries and truncated function argument values if argument capture is separately configured. Administrators should review enabled Perfbase extension feature flags before profiling sensitive workloads.</p>
<p>Extension installer and CDN: the plugin runtime does not call <code>cdn.perfbase.com</code>. The optional extension installer and manual extension binary downloads use <code>https://cdn.perfbase.com</code> only when a server administrator downloads or runs those installation assets.</p>
<h3>Privacy</h3>
<p>This plugin connects to Perfbase’s external service when profiling is enabled. It sends profiling trace data and request metadata to the configured Perfbase API endpoint.</p>
<p>Data submission requires explicit configuration of a Perfbase API key and the Enable Profiling setting. The plugin does not submit traces while profiling is disabled or while no API key is configured.</p>
<p>Administrators should review their site’s privacy policy and disclose their use of Perfbase where appropriate.</p>
