It is easier to follow the conversation. So, you're right. User.new vs. Factory.build(:user) should not be much difference in speed. Factory.build(:user) will instaniate the user (and its attributes) AND its associations, but should not be hitting the database. I would bring this up with the factory_girl folks.
