This comment here is what I come to HN for.

I think that OS X was the first OS that did hardware compositing. How come that WindowServer consumes so much CPU instead of GPU?

I didn't closely check for "is it CPU+GPU or CPU only" when I looked at Activity Monitor yesterday. I could, but I suspect that isn't a stable answer year-over-year yet.

The CPU isn't compositing, it's rendering 2D objects, I think—text, vector graphics, etc.
