People are replying that OP must own an old TV, but that's missing the point: with very old non-smart TVs, menu commands were always instantaneous!

Yeah, I don't understand why everyone is trying to invalidate their experience or suggest workarounds (implying that they are the problem); this isn't stackoverflow.

Every TV I have interacted with in recent years is slow and terrible, except for really old ones. The TVs are the problem, and we shouldn't be making excuses for that.

This was my experience with the switch from analog cable boxes to digital boxes. The whole experience became sluggish as channel changes were forced to wait for I-frames which depended on the GOP size.
