+##  Using Nginx as a reverse proxy and serve static resources directly
+We can tune the performance in splitting requests into categories static and dynamic. 
+
+CSS files, JavaScript files, images and web fonts are static content.
+The front page, a repository view or issue list is dynamic content.
+
+Nginx can serve static resources directly and proxy only the dynamic requests to gitea.
+Nginx is optimized for serving static content, while the proxying of large responses might be the opposite of that
+ (see https://serverfault.com/q/587386).
+
+Download a snap shot of the gitea source repository to `/path/to/gitea/`.
+
+We are only interested in the `public/` directory and you can delete the rest.
+
+Depending on the scale of your user base, you might want to split the traffic to two distinct servers,
+ or use a cdn for the static files.
