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.
Key Features
<ul>
<li>Performance Boost – Reduces menu rendering time with static file caching</li>
<li>Multiple Menu Support – Cache and display multiple menus independently on the same page</li>
<li>Horizontal & Vertical Layouts – Supports both menu orientations for flexible placement</li>
<li>Static File Generation – Pre-generates HTML files for instant delivery</li>
<li>Lazy Loading – Top-level items load instantly; submenus load on first hover</li>
<li>Smart Caching – Uses localStorage for even faster subsequent loads</li>
<li>Max Mega Menu Compatible – Fully supports complex mega menu layouts</li>
<li>Easy Integration – Simple shortcode implementation</li>
<li>Translation Ready – Full i18n support with included POT file</li>

</ul>

WP Meteor offers an original way to further optimize your website speed. 
With this plugin you can increase your PageSpeed score by up to 5x. 
The plugin is 100% free, it is compatible and works well with most popular caching plugins like: 
* Autoptimize 
* WP Rocket 
* WP Total Cache 
* WP Super Cache 
* Phastpress 
* LiteSpeed 
* Hummingbird

The few known incompatibilities are listed in the FAQ.
<h4>BENEFITS</h4>
WP Meteor can improve your <a href="https://pagespeed.web.dev/" rel="nofollow ugc">Pagespeed</a> results and the actual loading time of your website by up to 5x! You do not have to take our word for it, it only takes 2 minutes to install the plugin and <a href="https://test.fastpixel.io/" rel="nofollow ugc">test how it improves</a> your website speed. 
And since the plugin is designed to leave no traces on your hard drive or database when deactivated and removed, there is no risk for you.
<h4>HOW IT WORKS</h4>
If the user does not interact with the page immediately, WP Meteor defers loading and firing scripts until the page is rendered, which increases the pagespeed metric, on average, by 2-5x.
This delay in loading scripts greatly improves perceived load times for your visitors. It also significantly improves the following important SEO metrics:
<ul>
<li><a href="https://pagespeed.web.dev/" rel="nofollow ugc">Page Speed</a></li>
<li><a href="https://web.dev/lcp/" rel="nofollow ugc">Largest Contentful Paint (LCP)</a></li>
<li><a href="https://web.dev/tti/" rel="nofollow ugc">Time To Interactive (TTI)</a></li>
<li><a href="https://web.dev/tbt/" rel="nofollow ugc">Total Blocking Time (TBT)</a></li>
</ul>

WP Meteor Website Speed Optimization Addon

Let me cut to the chase. WP Meteror is an awesome plugin that actually worked for me and rocketed my score up according to Google Page Speed metrics.
Furthermore, It is fully compatible with Autoptimize and WP Super Cache, two great plugins which I persistently consider among “must-haves.” 
Being always frustrated with GPS scores, I was always looking for a way to minimize the damn “main thread work,” get rid of “render-blocking resources” and improve LCP, TTI and TBT (Ironically, Google still regards its own reCAPTCHA, Tag Manager, etc. as render-blocking or unused JavaScript!)
The optimization of JS files and applying Defer attribute to scripts, among many others, just led to a slight improvement in my score, no way comparable with that of WP Meteor.
Last but not least, using WP Meteor had some downsides on my website as Alex had clearly explained. But there is an inbuilt exclusion session which helped me exclude troublesome scripts easily.
In a nutshell, this plugin kills it on Page Speed and deserves 10 out of 5 stars!
