Wp Core Tools

<p>Speedix profiles PHP execution on your WordPress site, showing exactly which hooks and plugins are slow. Unlike page speed tests that just show load time, Speedix shows you <em>why</em> your site is slow.</p>
<p>Built for developers, agencies, and site administrators who need to diagnose performance issues at the code level.</p>
<h4>What It Does</h4>
<p>Measures every WordPress hook with microsecond precision and traces slow callbacks back to their source plugins using PHP Reflection. You get a clear breakdown of where time is spent: Core vs Theme vs Plugins.</p>
<p>The dashboard shows a health score (0-100), highlights the slowest hooks, and tracks performance trends over time. WooCommerce sites get a dedicated tab with categories for Checkout, Cart, Products, Orders, and more.</p>
<h4>Safe for Production</h4>
<ul>
<li>Sample rate control (10-100% of requests)</li>
<li>Threshold filtering to only log slow hooks</li>
<li>Overload protection auto-pauses if overhead spikes</li>
<li>Auto-cleanup from 1 hour to 7 days retention</li>
</ul>
<p>Quick presets let you switch between Safe Mode (10% sampling), Balanced, or Detailed profiling with one click.</p>
<h4>WooCommerce Support</h4>
<p>Works with HPOS (Custom Order Tables) and Cart/Checkout Blocks. Tracks checkout complexity: payment gateways, shipping methods, coupons, and session size.</p>
<h4>Export Options</h4>
<p>CSV, JSON, and Markdown exports for reporting and analysis.</p>
<h4>Why Not a Page Speed Test?</h4>
<p>GTmetrix and PageSpeed measure frontend delivery. Speedix measures server-side PHP execution. They answer different questions. Use both.</p>
<h4>Privacy</h4>
<p>All data stays in your WordPress database. No external API calls, no tracking, no telemetry. GDPR compliant by design.</p>
<h4>100% Free</h4>
<p>Every feature is included. No pro version, no upsells.</p>
