FindObjectOfType or FindWithTag

I have a GameObject which I keep between all scenes (what I believe is referred to as a singleton), and grab a reference to it using FindObjectOfType in Awake.

But the Unity Script Reference says that function is “very slow”, so I’m just wondering if FindWithTag and then a GetComponent on the script would save a considerable amount of processing time?

“Slow” is relative. We’re talking about computers, where “slow” could mean doing something “only” 10,000 times per second instead of 10 million times. If you’re just doing it in Awake, it doesn’t matter even a little bit.
