10Web Booster Pro

10Web Booster Pro is the paid speed optimization edition for WordPress websites. It covers frontend optimization across the entire site and its images, along with backend optimization, for desktop and mobile versions of websites of any complexity.

Caching and code processing

Page caching stores dynamic WordPress pages as static copies for faster retrieval. File caching stores minified and compressed scripts and styles. Pro also uses NGINX FastCGI Cache for resources such as pages, feeds, and 301 redirects on subdomains. Cache controls include invalidation and session-aware, browser-aware, device-aware, and cookie-aware caching.

CSS and HTML minification and compression reduce file sizes, and selected resources can be merged. JavaScript minification removes extra spaces, comments, and other nonessential code; scripts can also be combined. Optimization can defer JavaScript execution and prioritize critical CSS.

Images and other page resources

Image optimization compresses documents while preserving image quality. WebP conversion, container-specific resizing, and image preloading help deliver appropriately sized images. The feature set also includes image lazy loading, iframe and video lazy loading, and font swap.

What each speed mode adds

The four modes combine standard optimization techniques at different levels. Standard includes caching, code minification and compression, image optimization, lazy loading, font swap, WebP conversion, and container-specific image resizing. Balanced adds Critical CSS generation to Standard. Strong adds JavaScript delay to Standard. Extreme combines the Balanced functions with JavaScript delay.

During automated homepage optimization, the available modes are tested and compared. The mode with the highest score that keeps the website from breaking is set as the default. You can assign a different level to an individual page from the Custom rules tab in the 10Web dashboard.

Dashboard process

Switch to the Pro edition from the personal dashboard to manage optimization. Start with the homepage optimization, review the selected mode, then use Custom rules to adjust individual pages as needed. The dashboard also has a URL area for adding pages to optimize.
