More performance with "Set Actor Tick Enabled"?

In which situations can i effective use the function “Set Actor Tick Enabled”?

Hey Master Gebjeter-

Set Actor Tick Enabled is used for any actor that you need to tick/update during runtime. If an actor has no reason to tick, you can leave TickEnabled as false to save on performance. If Set Actor Tick Enabled is false, the actor’s Tick function is not called.
