Site speed and performance optimization don’t have to be a complex task. With Solid Performance, simply install and activate, and the plugin will incrementally create static versions of each URL of your website for an instant performance boost.
<h4>How Solid Performance Increases Your Site Performance and Page Speed ✅</h4>
You’re busy, and you need to spend time building your website. In order to build well you need a solid foundation. Installing Solid Performance lets you optimize your site performance right away and start building sooner and faster without having to spend time configuring dozens of options.
A solid caching solution should not cause breakage with your favorite plugins. Solid Performance comes out of the box with smart plugin exception rules for pages that have dynamic content created by these plugins: 
* WooCommerce 
* GiveWP
With these smart defaults and page caching in place automatically, you can focus your time and energy on building and enhancing your website instead of struggling through dozens of caching settings.
<h4>What is Caching and how does Solid Speed leverage it ❓</h4>
There are several different types of caching
Solid Performance focuses exclusively on page caching, grabbing the HTML of your WordPress URLs and storing that in a secure directory. Then, when your visitors arrive at your site, the browser doesn’t need to run through PHP or hit your database again, it just serves up the desktop or mobile (if enabled) versions of static HTML, CSS, and JS files fast and simply.
<h4>How Page Caching Benefits Your Website Performance 🚀</h4>
As soon as you activate Solid Performance, your site will get an immediate boost. You’ll see benefits like these: 
🚀 Improved site performance (content delivery speed) 
🚀 Reduced drag on server load 
🚀 Measurable, quantifiable stats: lower bounce rates and higher conversion rates
When a site developer or manager is able to improve site performance for a client (for example), they are able to provide improved SEO results and meet a widely accepted expectation that well-run sites do not have slow download or content delivery times.

Disclaimer: I do work for StellarWP. BUT, this plugin did speed up multiple sites I've installed it on, including my personal site devin.org



I suggest it for a "solid" page caching solution


Installed and it's like woah, fast fast fast

Solid Performance is a no-code solution for increasing the page performance of your WordPress website.

PlugoSpeed is a WordPress performance plugin that combines page caching, asset optimization, and Core Web Vitals improvements in a single lightweight package.
It generates static HTML cache files served directly from disk via Apache — bypassing PHP and WordPress on cached requests. In testing on a standard VPS, this approach achieves sub-50ms TTFB and PageSpeed scores of 95/100 on desktop.
A React 18 dashboard provides real-time cache hit rates, bandwidth saved, and PageSpeed score tracking — no jQuery required.
<h4>Core Features (Free)</h4>
Static HTML Cache 
Pages are stored as static <code>.html</code> files on disk. Apache serves them directly — no PHP, no database, no WordPress bootstrap. Cache TTL is configurable (default: 24 hours).
HTML Minification 
Removes unnecessary whitespace and comments from the final HTML output, reducing page size without affecting content or functionality.
CSS Minification 
Minifies stylesheet files inline, reducing transfer size. Combine is intentionally disabled by default for HTTP/2 compatibility.
JavaScript Defer 
Adds <code>defer</code> to non-critical scripts, improving Time to Interactive (TTI) and Largest Contentful Paint (LCP) scores on mobile.
Image Lazy Loading 
Adds native <code>loading="lazy"</code> to images and iframes below the fold. Injects explicit <code>width</code> and <code>height</code> attributes to reduce Cumulative Layout Shift (CLS).
Database Cleanup 
Scheduled cleanup of post revisions, auto-drafts, spam comments, and expired transients. Configurable schedule: daily, weekly, or monthly.
Cache Preloading 
After purge, PlugoSpeed re-warms the cache automatically by walking your XML sitemap. Rate-limited to avoid server overload.
Auto Cache Purge 
Cache is invalidated on post save, theme change, plugin activation, and WooCommerce stock/price updates.
PageSpeed Dashboard 
Tracks your Google PageSpeed Insights score over time with a 30-day graph. Shows live cache hit/miss ratio, bandwidth saved, and page count.
<h4>Pro Features</h4>
Remove Unused CSS (RUCSS) 
Generates a per-page stylesheet containing only the CSS rules that are actually used. Eliminates render-blocking CSS from page builders and plugin stylesheets. Requires a PlugoPress API key.
Critical CSS 
Inlines the above-the-fold CSS directly in <code><head></code>, eliminating render-blocking for a faster LCP. Requires a PlugoPress API key.
WebP Image Serving 
Automatically serves <code>.webp</code> versions of images to supported browsers, reducing image payload by 25–35% without quality loss.
