Descripción

Performance Optimisation helps you speed up your site with cache management, JavaScript and CSS minification, image conversion (WebP and AVIF), lazy loading, preload hints, and a modern admin UI. It is designed to stay off by default for aggressive options (defer/delay JS, WooCommerce asset removal, server rules) so you can enable features gradually and test as you go—similar to how you would tune Autoptimize or a caching stack, but with a focused, dashboard-first workflow.

Why use this plugin?

  • Clear scope: One place for cache stats, file optimisation, images, preload, and tools—without bundling unrelated features.
  • Safety-first UX: Advanced toggles show warnings; WooCommerce-related options remind you to test cart and checkout.
  • Core Web Vitals & PageSpeed: Lazy loading, minification, preconnect/prefetch, and image formats help real-world metrics—not just a higher score on a single lab test.

Features:

  • Dashboard with an overview of cache, JavaScript, CSS, and image optimisation status.
  • Cache management tools, including size display and a «Clear Cache» button.
  • JavaScript & CSS Optimization: Minify, combine, defer/delay (opt-in), and exclude specific files.
  • Core Tweaks: Safely disable Core bloat (Emojis, Embeds, Dashicons, XML-RPC, Heartbeat API).
  • Image optimization: Convert images to WebP and AVIF formats.
  • Preload settings for cache, fonts, DNS, and images.
  • Advanced lazy loading options.
  • Database Optimization: Clean database bloat manually or schedule automated cleanups (Daily/Weekly/Monthly) with granular control over post revisions.
  • Import/export plugin settings.

FAQ

Will this work with WooCommerce?

Yes. WooCommerce-specific asset removal is optional and off by default. If you enable it, test cart, checkout, and product pages—incorrect URL or handle exclusions can break the storefront.

Can I use this with another cache plugin (WP Super Cache, LiteSpeed, WP Rocket, etc.)?

You should run one full-page caching solution. This plugin can install a advanced-cache.php drop-in when appropriate; if another plugin or your host already manages that file, Performance Optimisation will not replace it and may show an admin notice. Minify/image features may still be usable depending on your stack—test carefully.

Does this plugin improve Core Web Vitals or PageSpeed Insights?

It can help when you enable features that address LCP, CLS, and JS blocking (lazy load, minify, preload, modern image formats). Results depend on your theme and other plugins; always measure before and after.

How do I optimize images using this plugin?

Go to the Image Optimisation Settings tab, enable image conversion, and choose the format (WebP, AVIF, or both). Click «Optimize Now» to start the process.

Can I exclude specific JavaScript or CSS files from minification?

Yes, in the File Optimization Settings tab, use the provided text areas to list files you want to exclude.

Does the plugin support lazy loading for images?

Yes, lazy loading can be enabled in the Image Optimisation Settings tab. You can also use SVG placeholders for better performance.

How can I import/export plugin settings?

Use the Tools section to export your current settings or import settings from another instance.
