Performance Optimisation

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.
• Enterprise Redis Support: High-availability Object Cache with Sentinel, Cluster, and TLS/SSL support.
• Performance Monitor: High-precision local telemetry for Core Web Vitals and network diagnostics.
• System Info Dashboard: Real-time environment diagnostic tool for PHP, DB, and WordPress.
• Import/export plugin settings.
