Hierarchy manipulations are really slow

Hello everybody,

I have a big speed problem with the hierarchy panel in Unity.

It takes several minutes to move a game object in it.
I must admit that my hierarchy contains thousand of objects…

Do you face the same problem?
What could be the cause of that?
What is Unity doing when we displace objects in the hierarchy?
Is there a way to improve the speed?


Group your objects in empty gameObjects and fold em up. Like if you’ve got 10000 cubes , make a new gameObject and call it ex. Cubes and place all the cubes in that game object . then click the arrow next to the Cubes game object in hierarchy to fold it up.

Hope this helps.
