You can write applications which talk to Rack directly, and that will be 
the fastest way to generate a response. I'm sure there's a "hello world" 
Rack example.

If you have this performance requirement in a real-world application, 
you can still use Rails. There is "Rails Metal" which lets you connect 
certain actions directly to Rack.
