I don’t want any framework. Although i have been looking at rails and am
extremely impressed.I just want to know the “fastest” way to execute ruby code in a web
server and display output.
Like a hacking challenge one could think of the problem.
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.
