-**55–73% of nginx throughput** on static files. Zero dependencies beyond PHP itself.
+### Why it's faster than nginx + php-fpm for real apps
+
+| | nginx + php-fpm | Qbix Server |
+|---|---|---|
+| 🚀 **PHP request speed** | 10–50ms bootstrap on *every* request | **0ms** — workers fork after classes are loaded |
+| 💾 **Memory** | 30–60MB × N workers (duplicated) | 30MB shared + ~5MB per worker (copy-on-write) |
+| 🔒 **Access-controlled files** | Public URLs or hacky rewrites | `X-Accel-Redirect` — PHP checks access, server streams the file |
+| 🧩 **Cache invalidation** | Whole-page only (purge everything) | `X-Cache-Tree` — invalidate one component, keep the rest cached |
+| 🌐 **WebSocket** | Needs a separate server | Built in |
+| ⚙️ **Setup** | Install nginx, configure proxy_pass, php-fpm pool, sockets... | `php qbixserver.php --port=8080` |
+
+Static file throughput is 55–73% of nginx (C will always beat PHP on raw I/O).  
+But on **actual PHP workloads**, the bootstrap savings make this **2–5x faster**.
+
+> 💡 You can always put nginx, a reverse proxy, or a CDN (Cloudflare, CloudFront)
+> in front of this for faster HTTPS and edge caching. Qbix Server handles the
+> PHP execution, access control, and intelligent caching behind it.
