-#### GZip Compression
-
-When files are precompiled, Sprockets also creates a
-[gzipped](http://en.wikipedia.org/wiki/Gzip) (.gz) version of your assets. Web
-servers are typically configured to use a moderate compression ratio as a
-compromise, but since precompilation happens once, Sprockets uses the maximum
-compression ratio, thus reducing the size of the data transfer to the minimum.
-On the other hand, web servers can be configured to serve compressed content
-directly from disk, rather than deflating non-compressed files themselves.
-
-NGINX is able to do this automatically enabling `gzip_static`:
-
-```nginx
-location ~ ^/(assets)/  {
-  root /path/to/public;
-  gzip_static on; # to serve pre-gzipped version
-  expires max;
-  add_header Cache-Control public;
-}
-```
-
-This directive is available if the core module that provides this feature was
-compiled with the web server. Ubuntu/Debian packages, even `nginx-light`, have
-the module compiled. Otherwise, you may need to perform a manual compilation:
-
-```bash
-./configure --with-http_gzip_static_module
-```
-
-If you're compiling NGINX with Phusion Passenger you'll need to pass that option
-when prompted.
-
-A robust configuration for Apache is possible but tricky; please Google around.
-(Or help update this Guide if you have a good configuration example for Apache.)

 ### Local Precompilation
 
 There are several reasons why you might want to precompile your assets locally.
