Worked: (newest version of Blender that worked as expected)
Short description of error
Object with hair system rotates slowly when it is not instanced. So I suppose, that something racalculates again and again with each movement.
Exact steps for others to reproduce the error
- Open attached file
- Unhide any of the collections
- Compare the speed to rotate the object with the instance.
The greater the number of child particles, the more evident the problem
