<p>This plugin implements gzip output compression to speed up load times.</p>
<p>The plugin also does a check to see if browsers are incorrectly saying that they do not support GZIP when they actually do. This can speed up load times for a significant portion of users.</p>
<pre><code>For requests with missing or mangled Accept-Encoding headers, inspect the User-Agent to identify browsers that should understand gzip.
* Test their ability to decompress gzip.
* If successful, send them gzipped content!
</code></pre>

<p>DietPress puts your WordPress on a diet and speeds it up. It pairs a complete set of performance optimizations (the ones that used to ship in “Zero Config Performance Optimization”) with a clean, risk-based interface to disable the WordPress features you do not use. Everything is configurable, and the performance optimizations are already on by default, so you can simply activate and enjoy a faster site, or fine-tune every detail.</p>
<blockquote>
<p><strong>Coming from “Zero Config Performance Optimization”?</strong> This is the same plugin, now called DietPress and fully configurable. All your previous optimizations stay active by default; you just gained a settings page and a whole new set of WordPress-diet options.</p>
</blockquote>
<p>By default WordPress loads functions, services and scripts that most sites do not need. They slow down loading times and consume hosting resources. DietPress lets you trim that fat and apply battle-tested performance tweaks, with a clear description of what each option does and what might break, organized by risk level so you always know what is safe.</p>
<h3>TWO THINGS IN ONE PLUGIN</h3>
<p><strong>1. Performance optimizations (on by default)</strong></p>
<ul>
<li>Automatic Critical CSS inlined in the head (optional experimental deferral of non-critical CSS)</li>
<li>JavaScript defer parsing with smart dependency handling</li>
<li>Image loading attributes safety net: lazy loading, decoding=async and fetchpriority for images that bypass core</li>
<li>Automatic image dimensions for better CLS scores (including picture elements)</li>
<li>Resource hints: preconnect and DNS prefetch for common third-party origins</li>
<li>Theme stylesheet, critical fonts and logo preloading for a faster LCP</li>
<li>Google Fonts display=swap</li>
<li>RSS feed optimization (cache headers and item limit)</li>
<li>Server rules in .htaccess: browser caching, GZIP and Brotli compression, immutable cache headers, CORS for fonts and keep-alive (master switch plus per-feature toggles)</li>
<li>Database maintenance: daily expired-transient cleanup and safe query optimizations</li>
</ul>
<p><strong>2. Put WordPress on a diet (risk-based, opt-in)</strong></p>
<ul>
<li><strong>Light</strong> (safe for any site): emojis, RSD/WLW tags, shortlinks, self-pingbacks, comment pagination, admin email check, and more</li>
<li><strong>Moderate</strong> (evaluate first): oEmbed, jQuery Migrate, Dashicons on the frontend, Global Styles and Duotone, remote block patterns, avatars and Gravatar, comment threading, and more</li>
<li><strong>Strict</strong> (site-specific): granular RSS feed control, Heartbeat API mode, post revisions and autosave, disable comments, XML sitemap, native lazy loading/fetchpriority, content types, and more</li>
<li><strong>Widgets</strong>: dashboard widgets (including third-party ones from Yoast, WooCommerce, Elementor, Jetpack, Wordfence, Rank Math, Gravity Forms), classic sidebar widgets, block-editor widgets and the Customizer</li>
</ul>
<h3>SCALE, PROFILES AND ANALYZER</h3>
<ul>
<li>Savings indicator: HTTP requests removed, CSS/JS saved and active optimizations at a glance</li>
<li>Quick profiles: Personal Blog, WooCommerce Store, Landing Page and Maximum Cleanup</li>
<li>Site analyzer: personalized recommendations based on your active plugins and content</li>
<li>Import and export your whole configuration as a JSON file</li>
</ul>
<h3>COMPATIBILITY AND EXTENSIBILITY</h3>
<p>The plugin includes filters for developers:</p>
<ul>
<li><code>dietpress_critical_css</code> – Customize the inline critical CSS</li>
<li><code>dietpress_critical_css_handles</code> – Define which CSS handles are critical</li>
<li><code>dietpress_skip_defer_script_handles</code> – Opt scripts out of the JavaScript defer</li>
<li><code>dietpress_skip_defer_style_handles</code> – Opt stylesheets out of the CSS deferral</li>
<li><code>dietpress_preconnect_hints</code> – Customize preconnect origins</li>
<li><code>dietpress_dns_prefetch_domains</code> – Customize DNS prefetch domains</li>
<li><code>dietpress_critical_fonts</code> – Define critical fonts to preload</li>
</ul>
<p><strong>Compatible with:</strong></p>
<ul>
<li>Well-coded themes and page builders (Divi, Elementor, Beaver Builder, Gutenberg)</li>
<li>Cache plugins (WP Rocket, LiteSpeed Cache, W3 Total Cache, WP Super Cache, etc.)</li>
<li>Security plugins (DietPress focuses on performance and deliberately leaves security to them; we recommend our free Vigilant)</li>
<li>CDNs (Cloudflare, StackPath, KeyCDN, etc.) thanks to CORS and Vary headers</li>
<li>WordPress Multisite</li>
</ul>
<h3>HOW TO VERIFY THE OPTIMIZATIONS</h3>
<ul>
<li><strong>Cache rules:</strong> check your <code>.htaccess</code> for a block marked <code># BEGIN DietPress</code> with <code>immutable</code> Cache-Control headers</li>
<li><strong>Logo preload:</strong> view page source and look for <code><link rel="preload" ... fetchpriority="high"></code> pointing to your logo</li>
<li><strong>Critical CSS:</strong> view source and look for <code><style id="core-diet-critical-css"></code> in the head</li>
<li><strong>Compression:</strong> test at <a href="https://www.giftofspeed.com/gzip-test/" rel="nofollow ugc">giftofspeed.com/gzip-test</a></li>
</ul>
<p>Always measure with tools like Google PageSpeed, GTMetrix or WebPageTest, and run each test at least twice to account for caching.</p>
