Why would a totalitarian government be considered to be more efficient at making decisions than a democratic one?

Although a totalitarian government is generally considered an unproductive and harmful idea, a totalitarian government would be considered more efficient at making decisions than a democratic one, because a democratic government makes decisions based on the people making the decisions through representation of all the different peoples. A totalitarian government, on the other hand, is a political system in which one person holds total control over the state. This would mean that the person would make all the decisions without needing anyone's consent and this would be more efficient, as decisions would be made quicker.
