Menu Optimizer is a powerful performance optimization plugin that generates static HTML files for your WordPress menus, dramatically reducing server load and improving page load times.
Real-World Success: This optimization technique helped achieve the first WooCommerce store with a perfect 100/100 mobile score on Google PageSpeed Insights. <a href="https://wp-rocket.me/blog/100-mobile-score-woocommerce/" rel="nofollow ugc">Read the WP Rocket case study</a>
Why Menu Caching Matters
Menu generation requires significant compute time on WordPress and WooCommerce sites. Every page load requires WordPress to: 
* Query the database for menu items 
* Process menu hierarchy 
* Apply filters and hooks 
* Render HTML output
Menu Optimizer eliminates this overhead by pre-generating menu HTML files that are served instantly.
The DOM Size Problem
Google Lighthouse triggers warnings when a page exceeds 1,500 DOM nodes (HTML elements). For e-commerce sites with extensive product categories:
<ul>
<li>A mega menu with 200-300 categories can generate 3,000-5,000+ DOM elements</li>
<li>Each nested menu item multiplies the element count</li>
<li>This exceeds Google’s limits and hurts Core Web Vitals scores</li>
</ul>
Menu Optimizer’s lazy loading keeps your initial DOM size under 1,500 nodes by loading only top-level items (typically 50-100 elements). Submenus load on-demand, maintaining excellent performance.

Flying Pages preload pages before the user click on it, making them load instantly
<h3>How it Works?</h3>
Flying Pages injects a tiny JavaScript code (1KB gzipped), waits until the browser becomes idle. Then it detects pages in the viewport and on mouse hover and preloads them.
Flying Pages is intelligent to make sure preloading doesn’t crash your server or make it slow.
<ul>
<li>
Preload pages in the viewport – Detect links within the viewport (current viewing area) using ‘Intersection Observer’ and tells the browser to preload them using ‘prefetch’, switch to xhr if not available (similar to <a href="https://github.com/GoogleChromeLabs/quicklink" rel="nofollow ugc">Quicklink</a>).
</li>
<li>
Preload pages on mouse hover – On hovering links, if it’s not preloaded yet using above ‘viewport’, then Flying Pages will prefetch them instantly (similar to <a href="https://instant.page/" rel="nofollow ugc">Instant.page</a>).
</li>
<li>
Limits the number of preloads per second – If your page has too many links, prefetching all at the same time will cause the server to crash or slow down the website to visitors. Flying Pages limits the number of preloads per second (3 req/sec by default) using an in-built queue. For example, if you’ve 10 links in the viewport, preloading all these are span into 4 seconds.
</li>
<li>
Stops preloading if the server is busy – In case the server starts to respond slowly or return errors, preloading will be stopped to reduce the server load.
</li>
<li>
Understands user’s connection and preferences – Checks if the user is on a slow connection like 2G or has enabled data-saver. Flying Pages won’t preload anything in this case.
