The new accessibility javascript in the Appearance > Menus panel in WordPress 3.6 can significantly slow the page load speed when using a large number of menu items (> 50). This plugin defers the accessibility processing to eliminate the scripting bottleneck and allow the Appearance > Menus screen to run much faster and more responsively.

This solution is fairly rough. Hopefully we can develop a robust solution that can eventually become part of the core. Pull requests through GitHub are welcome.

Faster Appearance – Menus

Monitor and debug WordPress performance issues with DebugHawk – the performance monitoring tool built specifically for WordPress developers and site owners who need to identify what’s slowing down their site.
<h4>Why WordPress Sites Are Slow</h4>
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.
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.
<h4>What DebugHawk Monitors</h4>
Frontend Performance Metrics:
<ul>
<li>Core Web Vitals – LCP (Largest Contentful Paint), INP (Interaction to Next Paint), CLS (Cumulative Layout Shift), TTFB (Time to First Byte), FCP (First Contentful Paint)</li>
<li>Network Performance – DNS lookup time, connection time</li>
<li>Browser Resources – HTTP requests, page weight, transfer sizes</li>
</ul>
Backend Performance Tracking:
<ul>
<li>Database Query Performance – Slow queries, query count, total database time</li>
<li>PHP Execution – Execution time, memory usage</li>
<li>External HTTP Requests – API call timing, external service performance</li>
<li>Object Cache Performance – Hit ratio, cache effectiveness</li>
<li>Page Cache Effectiveness – Cache hits vs misses</li>
<li>Redirect Detection – Unnecessary redirects slowing page loads</li>
</ul>
<h4>Debug Slow WordPress Sites</h4>
Unlike generic performance tools, DebugHawk understands WordPress architecture. It shows you:
<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>
Perfect for WordPress developers, agencies managing multiple sites, and site owners who need to diagnose performance issues quickly.
<h4>How It Works</h4>
<ol>
<li>Automatic Monitoring – Once configured, DebugHawk tracks performance on every page load</li>
<li>Real User Monitoring (RUM) – See actual performance data from your real visitors, not synthetic tests</li>
<li>Historical Data – Track performance over time, identify when issues started</li>
<li>Encrypted Transmission – All data is encrypted before sending to DebugHawk’s dashboard</li>
</ol>
No impact on site performance – the monitoring overhead is negligible.
<h4>Perfect For</h4>
<ul>
<li>WordPress Developers debugging slow queries and performance bottlenecks</li>
<li>Agencies monitoring client site performance across multiple WordPress sites</li>
<li>Site Owners who need to understand why their WordPress site is slow</li>
<li>WooCommerce Stores tracking checkout performance and database optimization</li>
<li>Membership Sites 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>
