xSpeed Pro brings WordPress page caching, asset optimization, database tools, and assisted site management together. Its AI-powered audit scans a site and identifies performance options to review, with severity ratings and concrete reasons.

Serve pages from cache

The plugin saves pages as static HTML. On a cache hit, its static-file rewrite path serves the file before WordPress loads, bypassing PHP. The static-file rewrite path works with Apache, nginx, and LiteSpeed. The cache can rebuild after publishing or updating content, comments, plugins, or themes.

• Purge the cache from the WordPress admin bar with one click.
• Exclude URLs such as cart, checkout, and account pages.
• Choose an expiry from 1 to 720 hours, keep a separate cache for mobile users, and set custom rules for individual posts.

Optimize assets and database

xSpeed Pro can minify HTML, CSS, and JavaScript, combine CSS and JavaScript files, defer or delay JavaScript, and load CSS asynchronously. Other tools include GZIP compression, lazy loading for pictures, videos, and iframes, font optimization, and browser caching. CDN support includes URL rewriting and Cloudflare integration. Redis or Memcached can provide persistent object caching.

Database tools can optimize tables and remove post revisions, spam, trashed entries, transients, and orphaned metadata. Options to disable unused WordPress capabilities include frontend Dashicons, oEmbed, RSS feeds, XML-RPC, jQuery Migrate, and REST API authentication headers.

Review changes with the audit and optimization tools

The AI audit identifies functions that may help the specific site and explains its findings. 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.

Manage settings through MCP

The WordPress MCP server lets an AI assistant or another MCP client use site performance tools, including cache purging, preloader status, score runs, optimization, and settings reads or updates. Read-only connections remain read-only. Credential writing requires explicit permission when connecting.

Getting started

Install xSpeed Pro on the WordPress site, review the audit findings, and configure caching and exclusions for pages that should not be cached. Use the scoring and optimization tools to check changes as you tune the site's settings.
