Script/runner vz Rake tasks

When it comes to running Rails tasks the common question that comes to mind is whether to use script/runner or to call a rake task

script/runner long_running_task

VZ

rake long_running_task

To understand it better we need to understand how both works under the hood.

Whenever script/runner is called it boots the entire Rails

But on the other hand Rake task doesn't load the entire Rails app unless you tell it to by making the task depend on :environment, like this:

task :some_useful_task => :environment do
  # do some useful task
end

Since booting your Rails app is expensive each time, it might be worth skipping if you can avoid it.
