Ruby/Rails db connection pool implementation

Question

I have a ruby on rails application that takes a user http request, connects to the database, and sends back the response. To make the application faster, I would like to implement the db connection pool to avoid creating a new connection every time. I tried looking into the connection pool library, but did not fully grasp how to use it. Any help or pointers would be highly appreciated? Thanks.

ActiveRecord is the default ORM library that Rails uses and it automatically handles connection pooling for you so unless your using some other library you don't need to do anything.

Some of the pool options are configurable if you feel like you need to mess with them but I doubt you would http://api.rubyonrails.org/classes/ActiveRecord/ConnectionAdapters/ConnectionPool.html
