Checkout Profiler for WooCommerce

Wondering whether your WooCommerce checkout is slow? This plugin will tell you.

<p>MySQL Profiler displays debugging information about SQL queries to admin WordPress users.  For each query, the profiler displays the time, syntax-highlighted SQL, and a trace of the functions (as well as the file and line number that the functions were called from) that were called.</p>
<p>The list can be sorted by any of its columns, so you can, for example:</p>
<ul>
<li>Order the list by ID to see the chronological order of the queries</li>
<li>Order the list by time to see the slowest queries</li>
<li>Order the list by query to group the queries by type (SELECT, UPDATE, etc)</li>
<li>Order the list by trace to group the queries by similar origins</li>
</ul>
<p>The list can also filtered by typing in the search box, so you can, for example:</p>
<ul>
<li>View all queries that use the wp_posts table</li>
<li>View all queries that are related to the use of a function in taxonomy.php</li>
<li>View all queries that are related to the use of a specific function or class</li>
<li>View all queries that call a specific MySQL function</li>
</ul>
<p>To turn off syntax highlighting, put the following in wp-config.php:</p>
<pre><code>define('MP_HIGHLIGHT_SYNTAX', false);
</code></pre>
<p>To omit the file and line number from the function trace and display the functions as a comma-separated list (to save vertical space), define the following in wp-config.php:</p>
<pre><code>define('MP_DISPLAY_FILES', false);
</code></pre>
<p>This plugin was loosely based on <a href="http://bueltge.de/" rel="nofollow ugc">Frank Bueltge</a>‘s <a href="https://wordpress.org/extend/plugins/debug-queries/" rel="ugc">Debug Queries</a> plugin, so a hearty thanks to him for the development of that.</p>
