Unity3d - Call public static variable performance

I want to know if I call a public static variable from another script in Update or FixedUpdate function , is that affect on performance ?

something like :

[RequireComponent(typeof(Rigidbody))]

public class CC : MonoBehaviour
{
    //Components
    public static Rigidbody rigidbodys;

    void Awake()
    {
        rigidbodys = GetComponent<Rigidbody>();
        rigidbodys.freezeRotation = true;
        rigidbodys.useGravity = false;
        rigidbodys.isKinematic = true;
    }
}

And in another script :

void FixedUpdate()
{
      if(CC.rigidbodys.velocity > 1)
          {
            DoSomething();
          }
}

If I use this way, will reduce performance or not?

That looks very good. In your Fixed Update you only access the rigibody (which is set once in awake) and this is cheap. You can also make a normal public Rigidbody rigbdy and pass your configured gameobject in the inspector. Then you can pass the content to your static Rigidbody. So you clean up the Awake. 

    void Awake()
    {
        rigidbodys = ridbdy;
    }

From perfromance side (> means better): static > Singleton Pattern > GetComponent/FindObject

As long as you keep you getComponent() out of update(), it would be faster than, for example, calculating the velocity in the other script.
