Default js included in Rails

When creating a new Rails application, it is automatically supplied with several quite large js files. In the application layout, by default, all of them are loaded into the page:

<%= javascript_include_tag :defaults %>

I was wondering, isn't loading all those javascripts can make the site possibly mush slower?
And if so, where can I change the definition of :defaults? Or should I just include the ones I need and remove the code line mentioned above?

Thank you

In config/application.rb

# JavaScript files you want as :defaults (application.js is always included).
config.action_view.javascript_expansions[:defaults] = %w(jquery.js rails.js)

Using :defaults is not mandatory in any way. If you are worried about performance you should read at least the caching part from javascript_include_tag docs:
