<h4>Only for development!</h4>
<h4>Now with OPcache memory consumption support</h4>
<p>This plugin dumps the colorized filenames and memory consumptions or file sizes after the normal WordPress HTML output, after the closing html tag. This generates invalid HTML but gives you an overview of loaded plugins and the current theme.</p>
<p><em>What’s running</em> lists all files parsed and executed by the PHP engine. It can be used for plugin or theme refactoring.</p>
<h4>Now you can highlight your own plugin and theme</h4>
<p>Provide a part of its path in wp-config.php:</p>
<pre><code>define( 'WHATS_RUNNING_HIGHLIGHT', 'wp-content/plugins/my-plugin' ); </code></pre>
<h4>Color codes</h4>
<ul>
<li>your code is highlighted with YELLOW background</li>
<li>plugin files are in BLUE</li>
<li>themes files are in ORANGE</li>
<li>files in the wp-includes directory are in GREEN</li>
<li>files in the wp-admin directory are in GREY</li>
<li>all other files are in RED</li>
<li>VIOLET bar after the filename represents the file size ( 0.5 kB/px )</li>
<li>DARK MAGENTA bar after the filename represents the OPcache memory consumption ( 1 kB/px )</li>
</ul>

What's running

Lists WordPress require() calls mainly for plugin code refactoring.

Konstantin Kovshenin

<p>This plugin lists the top 100 slowest actions and filters during a page request in WordPress. It helps you figure out performance bottlenecks in themes and plugins.</p>
<p>Requires <a href="https://wordpress.org/plugins/debug-bar/" title="Debug Bar" rel="ugc">Debug Bar</a>.</p>
<p>Current limitations:</p>
<ul>
<li>Does not time nested actions and filters due to a core bug</li>
<li>Does not time actions and filters before plugins_loaded or muplugins_loaded if placed in mu-plugins</li>
<li>Does not time actions and callbacks after wp_footer at priority 1000</li>
</ul>


Debug Bar Slow Actions

many thanks to author. Excellent plugin!



MUST-HAVE for every developer.

Great!

This plugin is essential for plugin development! It also works with the Query Monitor plugin.

Indispensable!

Easily find out which actions and filters are the slowest during a page load.
