# Features — xSpeed

> Every performance feature in one lightweight WordPress plugin. From static page caching to an AI intelligence layer — everything works together, nothing fights for resources.

## Caching — served before WordPress even loads

Page, mobile, browser and object caching working as one. Static HTML is delivered before PHP starts — no database, no plugin chain — and rebuilt automatically when you publish.

- Page & mobile cache with per-post rules
- Browser cache headers for instant repeat visits
- Redis / Memcached object cache backends

## Optimization — smaller, fewer, faster assets

Minify and combine HTML, CSS and JS, defer or delay scripts, and load CSS asynchronously — all with a safe-minify fallback that auto-skips anything that could break.

- Minify + combine with safe-minify fallback
- Defer / delay JS, async & Critical CSS (Critical CSS is Pro)
- Font swap, preload & lazy-loaded media

## Delivery — closer to every visitor

GZIP compression auto-configures on Apache and LiteSpeed, with copy-paste snippets for nginx and IIS. CDN rewrite and Cloudflare integration push assets to the edge with automatic purging.

- GZIP on Apache & LiteSpeed, snippets for nginx
- CDN URL rewrite (Pro)
- Cloudflare auto-purge & dev-mode toggle

## Intelligence (Pro) — the AI layer that tunes itself

Pro adds a brain on top of the engine: it scores your site, finds what's slow, and fixes it. Frequently-missed URLs get warmed, conflicts get auto-resolved, and stale cache heals itself.

- Recommendations engine & Performance Score
- Frequently-missed URLs & per-URL heatmap
- Self-healing cache & plugin-conflict auto-resolution
