Question

I am trying to boost speed. I tested on gtmetrix and got the following results:

There are some plugins for this in Wordpress, but I don't know how to do it in ROR.

Do you know what it means and how I can achieve this in Ruby on Rails?

Answer 1

This is to indicate to Sprockets that the version of the file to retrieve is the non-precompiled version for debugging.

You can get rid of that in your config/environments/development.rb or production.rb or your_environment.rb with:

config.assets.debug = false

This option is true by default in the development environment, so I guess you are testing in that mode.
