Is GetComponent<>() slow?

Question

I have an array of GameObjects with a MyScript component attached to each. Every frame I need to update a value in MyScript in each of the GameObjects. Is calling GetComponent<>() each frame for each object going to be slow? Should I create a separate array of MyScript components of the corresponding GameObjects instead?

Ok, so I'm not sure. In my case the answer would be - no, it's not worth caching?

Yeah I'd cache it in Start or Awake as a matter of course (but I'm not sure that this is easy in your case), just for the hell of it. If you've only got a few you'll not notice.
