Thin VS Goliath

This one file contains everything needed for this simplified app to run. Run it with ruby main.rb, which should spin up an instance of the Thin web server (the default web server that comes with Sinatra). Visit localhost:4567 and you'll see the JSON response.

The other major thing you'll run into is performance. WEBrick's HTTP parsing code may look hairy but it is fast. Mongrel was the first Ruby HTTP server to implement it's HTTP parser in C using Ragel, which Thin, Unicorn, and Puma all copied; although there's a bug in the original Mongrel HTTP parser where it does not combine the values duplicate HTTP headers (yes, HTTP Header names can actually be repeated).

Now let's run our application using a different server. We'll use Thin, a small, simple, and fast web server.

The Goliath project can be accessed through its GitHub repository page. Goliath boasts a powerful feature of decluttering the complicated asynchronous requests into a linear execution communication process. The asynchronous mechanism of Goliath can hence be used very quickly for streaming the data, firehose API, etc. Also, Goliath is open-source, which has been a significant factor in its linear development over time. If you are into web-server development in Ruby, you will love working in Goliath.
