英文：Use 'Thin' as your default Server in Rails App
Rails comes with 'WeBrick Server' to run your Rails Application. When you run 'rails s' in your terminal, by default WeBrick will run.
If you want to have a thinner lighter and faster version of the rails server, you can use an alternative rails server 'thin'
To Install it add this to your GemFile
gem 'thin'
Do a
bundle install
And then run 'thin' rails server in your terminal as
rails server thin
Thats it....
