<p>Almost every developer knowns that the poor performance in many cases is due to poorly designed database or SQL queries<br />
(for example, when the table does not have indices that the query can use or when the query uses unnecessary<br />
performance killers such as ORDER BY/GROUP BY).</p>
<p>WordPress can provide only the list of the queries and the developer has to manually run every query and analyze it.<br />
Very boring, isn’t it? SQLMon tries to help the developers and analyzes the query itself, reporting everything that needs attention.</p>
<p>Every query passed to WordPress is analyzed (using EXPLAIN) and the results are shown in the theme’s footer or Admin panel’s footer<br />
(they are visible to site administrators only — this allows to use SQLMon even on live sites).</p>
<p>One of the key features of SQLMon is that it can run EXPLAIN not only on SELECT queries but also on UPDATE/DELETE and INSERT/REPLACE INTO … AS or<br />
CREATE TABLE … AS.</p>
<p>The plugin is perfect for WordPress developers, plugin and theme authors and site administrators who are trying to find out why the blog is too slow.</p>
<p><strong>IMPORTANT:</strong> the project has moved to <a href="https://launchpad.net/wp-plugin-sqlmon" rel="nofollow ugc">Launchpad</a>, please use it to report all bugs, suggest improvements,<br />
request features and get the latest development version.</p>
<h3>Warning</h3>
<p>This plugins requires that PHP 5 be installed.<br />
No support for ancient PHP 4, sorry.</p>
<h3>Incompatibilities</h3>
<p>SQLMon is incompatible with plugins that install their own <code>db.php</code> into <code>wp-content</code> directory (DB Cache, DB Cache Reloaded, probably W3 Total Cache).</p>
<h3>Removal</h3>
<p>If you want to remove the plugin completely, please deactivate it first and make sure that <code>wp-content/db.php</code> is deleted (if not, please delete it yourself).</p>

<p><strong>Monitor and debug WordPress performance issues with DebugHawk</strong> – the performance monitoring tool built specifically for WordPress developers and site owners who need to identify what’s slowing down their site.</p>
<h4>Why WordPress Sites Are Slow</h4>
<p>Slow WordPress sites lose visitors, conversions, and search rankings. But identifying the root cause is difficult when frontend tools like Google PageSpeed Insights only show part of the picture.</p>
<p>DebugHawk monitors both frontend and backend performance so you can see exactly what’s slowing down your WordPress site – whether it’s slow database queries, external API calls, or frontend Core Web Vitals problems.</p>
<h4>What DebugHawk Monitors</h4>
<p><strong>Frontend Performance Metrics:</strong></p>
<ul>
<li><strong>Core Web Vitals</strong> – LCP (Largest Contentful Paint), INP (Interaction to Next Paint), CLS (Cumulative Layout Shift), TTFB (Time to First Byte), FCP (First Contentful Paint)</li>
<li><strong>Network Performance</strong> – DNS lookup time, connection time</li>
<li><strong>Browser Resources</strong> – HTTP requests, page weight, transfer sizes</li>
</ul>
<p><strong>Backend Performance Tracking:</strong></p>
<ul>
<li><strong>Database Query Performance</strong> – Slow queries, query count, total database time</li>
<li><strong>PHP Execution</strong> – Execution time, memory usage</li>
<li><strong>External HTTP Requests</strong> – API call timing, external service performance</li>
<li><strong>Object Cache Performance</strong> – Hit ratio, cache effectiveness</li>
<li><strong>Page Cache Effectiveness</strong> – Cache hits vs misses</li>
<li><strong>Redirect Detection</strong> – Unnecessary redirects slowing page loads</li>
</ul>
<h4>Debug Slow WordPress Sites</h4>
<p>Unlike generic performance tools, DebugHawk understands WordPress architecture. It shows you:</p>
<ul>
<li>Which plugins are causing slow database queries</li>
<li>Which external APIs are timing out</li>
<li>Whether your caching is working effectively</li>
</ul>
<p>Perfect for WordPress developers, agencies managing multiple sites, and site owners who need to diagnose performance issues quickly.</p>
<h4>How It Works</h4>
<ol>
<li><strong>Automatic Monitoring</strong> – Once configured, DebugHawk tracks performance on every page load</li>
<li><strong>Real User Monitoring (RUM)</strong> – See actual performance data from your real visitors, not synthetic tests</li>
<li><strong>Historical Data</strong> – Track performance over time, identify when issues started</li>
<li><strong>Encrypted Transmission</strong> – All data is encrypted before sending to DebugHawk’s dashboard</li>
</ol>
<p>No impact on site performance – the monitoring overhead is negligible.</p>
<h4>Perfect For</h4>
<ul>
<li><strong>WordPress Developers</strong> debugging slow queries and performance bottlenecks</li>
<li><strong>Agencies</strong> monitoring client site performance across multiple WordPress sites</li>
<li><strong>Site Owners</strong> who need to understand why their WordPress site is slow</li>
<li><strong>WooCommerce Stores</strong> tracking checkout performance and database optimization</li>
<li><strong>Membership Sites</strong> monitoring server load and query performance</li>
</ul>
<h4>Get Started</h4>
<ol>
<li>Sign up for a free trial at <a href="https://debughawk.com" rel="nofollow ugc">DebugHawk.com</a></li>
<li>Install and activate this plugin</li>
<li>Add your site configuration to <code>wp-config.php</code></li>
<li>Start monitoring your WordPress performance</li>
</ol>
