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.

Stop guessing about your site’s performance. Rayetun Site Monitor gives you real-user Core Web Vitals data collected directly from your visitors’ browsers — no external account, no API key, no tracking from third parties.
Activate it. Visit a few pages. Within seconds you’ll see live performance metrics on your WordPress dashboard.
<h3>⚡ Why This Plugin?</h3>
Unlike Search Console (which shows aggregated, delayed data), Rayetun Site Monitors every page in real-time from the moment of activation. No sample-size thresholds. No waiting for Google to collect data. Just instant, actionable insights.
<ul>
<li>🎯 Zero configuration — activate and data flows immediately</li>
<li>📊 Real users, real data — field metrics from actual visitors (not synthetic robots)</li>
<li>🔒 Your data stays yours — everything lives in your WordPress database</li>
<li>⚡ No impact on performance — sub-4KB beacon, loaded with defer, zero blocking</li>
<li>🔐 GDPR-friendly — no cookies, no third-party data sharing</li>
</ul>
<h3>📈 What It Measures</h3>
The plugin tracks all five Core Web Vitals and presents them with Google’s official thresholds:
 Metric 
 Target 
 What It Means
 LCP — Largest Contentful Paint 
 ≤ 2.5s 
 How fast your main content appears
 CLS — Cumulative Layout Shift 
 ≤ 0.1 
 How stable your page layout stays
 INP — Interaction to Next Paint 
 ≤ 200ms 
 How responsive your site feels to clicks
 FCP — First Contentful Paint 
 ≤ 1.8s 
 How fast anything appears on screen
 TTFB — Time to First Byte 
 ≤ 800ms 
 How quick your server responds
<h3>🖥️ The Dashboard</h3>
A single glance tells you everything about your site’s performance:
<ul>
<li>Score cards — P75 value per metric with color-coded Good / Needs Improvement / Poor badges</li>
<li>Distribution bars — see at a glance what % of page loads fall into each rating band</li>
<li>Sparkline trend charts — watch how each metric improves (or worsens) over 7, 14, or 30 days</li>
<li>Slowest Pages ranking — which URLs need the most work, sorted by LCP</li>
<li>Device split — toggle between All Devices, Mobile Only, or Desktop Only</li>
<li>Date range & URL filters — drill into specific time periods and individual pages</li>
</ul>
<h3>🔍 LCP Element Attribution</h3>
“My LCP is slow. But what is slow?”
Rayetun Site Monitor answers that automatically. The beacon captures the exact DOM element responsible for Largest Contentful Paint — whether it’s a hero image, a video embed, a heading, or a background. See the element tag, CSS class, and image source right alongside the metric.
No guesswork. No DevTools digging. Just answers.
<h3>🧪 PageSpeed Insights Lab Tests</h3>
Click PSI ↗ on any page row and Google’s lab test runs instantly inside your WordPress admin. Compare your real-user data (Field LCP P75) with Google’s synthetic lab test in a single view:
<ul>
<li>Lab performance score</li>
<li>Lab metrics: LCP, FCP, CLS, TBT</li>
<li>Field LCP P75 (real-user percentile)</li>
<li>Failed Opportunities list (unused JS, render-blocking resources, unoptimized images)</li>
<li>One-hour result caching to stay under API limits</li>
</ul>
No plugin configuration needed — the plugin works without an API key. Add a free key to get 25,000 requests/day instead of 25.
