Performance Issue When Applying animator.rootRotation

Hi there,

I'm having a performance issue with root motion driven characters, specifically with the following code, which is needed when using Mecanim with the NavMeshAgent.

 void OnAnimatorMove() 
 { 
     navMeshAgent.velocity = animator.deltaPosition/Time.deltaTime;
     transform.rotation = animator.rootRotation;
 }

The profiler looks like this with 32 characters in the game:

This seems like way too much for just setting a rotation.

Is there anything I can do to help performance?
