How to optimize animations?

Question

Game development

Good day to all.
I have a game object in the scene with a rigidbody2d that has isKinematic checked, and also a collider with isTrigger checked. Its transform is controlled by the animator.
If you add, for example, 20 such objects to the scene, you can observe the following picture:
If you turn off their animator or collider, we get:
Google says that the point is that the collider is constantly recreated during animation, since the animator affects the object through transform.
Actually, how should the object be configured correctly?

Answer 1

1) Try to simplify the shape of the collider - make it a box, not a polygon
2) Colliders are unlikely to be recreated - just update the physics.
3) Set up physics layers - who should trigger collisions with what.
