Performance Suite

Boosts speed, enhances user experience.

A must-have speed optimization extension for every Joomla website.

DotsCastle Performance Suite speeds up your site safely - without breaking layouts or extensions.

Clean, balanced optimization. No breakage.

Turn it on. Your site gets faster.

Image Optimization

• Automatic WebP conversion - JPG, PNG and GIF converted on first visit and cached for future requests
• Automatic AVIF conversion - up to 50% smaller than WebP, served only to supported browsers
• element wrapping with AVIF/WebP source sets and original fallback
• Automatic width & height injection to eliminate CLS (layout shift)
• Optional image resizing with configurable maximum width
• Privacy-Focused EXIF Metadata Stripping - removes hidden GPS coordinates, camera model details, device information and other embedded metadata to reduce file size and prevent accidental data exposure
• Per-image exclusion patterns

Lazy Loading

• Native loading="lazy" for all below-fold images
• Smart LCP detection — automatically applies loading="eager" to the first visible image to protect Largest Contentful Paint
• Configurable above-fold image count

JavaScript Optimization

• Defer non-critical scripts to unblock rendering
• Delay third-party scripts until user interaction
• Inline script minification
• Configurable exclusion patterns for critical scripts (jQuery, Bootstrap, etc.)

CSS Optimization

• Minify individual stylesheets
• Combine multiple stylesheets into a single request
• Configurable exclusion patterns

Font Optimization

• Asynchronous Google Fonts loading to eliminate render-blocking font requests
• Automatic font-display: swap injection for faster text rendering

Head Optimization

• LCP preload hint injection for the hero image
• Optimized element order (charset → viewport → preload → preconnect → CSS → styles)

HTML Optimization

• Optional HTML minification - removes excess whitespace
• Optional HTML comment stripping

Performance Dashboard

• Built-in stats dashboard inside plugin settings
• Tracks WebP & AVIF conversions, space saved, cache size and file counts
• One-click Clear Cache and Reset Stats actions

CLI Bulk Converter

• php cli/joomla.php dcperformance:bulk - convert all images before visitors arrive
• --force flag to reconvert after quality changes
• --dry-run flag to preview without writing files
• --dir flag to target a specific image subdirectory
