xSpeed Pro

xSpeed Pro brings WordPress caching, code optimization, asset delivery, and site analysis into one set of tools. Its AI-powered audit scans the website and identifies performance features to review, with severity ratings and reasons for its recommendations.

Set up and review performance changes

Install xSpeed Pro on the WordPress site you want to optimize, then review the setup settings and audit results. The optimization tool measures the site, applies recommended settings one at a time, checks the page after each change, and reverts a change if it breaks the site.

Serve cached pages before WordPress loads

xSpeed Pro saves pages as static HTML files. On a cache hit, its static-file rewrite path serves the file before WordPress loads, bypassing PHP. The path is described as supporting Apache, nginx, and LiteSpeed.

• Automatically purge the cache after publishing or updating content, comments, plugin updates, and theme changes.
• Purge from the WordPress admin bar, or exclude specific URLs such as cart, checkout, and account pages.
• Choose an expiry from 1 to 720 hours and keep a separate cache for mobile users.
• Set cache rules and custom expiry per post, or disable caching for an individual post.

Optimize code and asset delivery

Minify HTML, CSS, and JavaScript by removing unnecessary whitespace, comments, and characters. Other listed tools include GZIP compression, lazy loading, font optimization, browser caching, CDN support, object caching, and database cleanup.

Options to disable unused WordPress features include frontend Dashicons, oEmbed, RSS feeds, XML-RPC, jQuery Migrate, and REST API authentication headers. Review these options against the needs of your site before enabling them.

Connect an assistant through MCP

The WordPress MCP server lets an AI assistant or another MCP client use xSpeed tools to inspect and manage the site. Available operations include purging the cache, checking preloader status, running a score, optimizing the site, and reading or updating settings. Read-only connections remain read-only; writing credentials requires explicit permission when connecting.

Check settings for your site

Start with caching and the audit recommendations that fit your site. Configure exclusions for pages that should not be cached, then use the available scoring and optimization tools to review changes.
