It is pretty well optimized. I think it might not be, like, genius-level amazing, but the devs care about performance and worked to improve it.
In the end though, it’s a game where the entire map (as generated so far) is simulated - I think there’s cases where chunks go to sleep, but it’s not Minecraft’s “stop simulating anything not next to a player”. When combined with players building lots of machines moving many, many items around, you’ll inevitably end up with some serious CPU usage. Not a problem on a decent computer, but I have had friends struggle on weak laptops, even getting dropped as they literally couldn’t keep up with the server.

You can always use the gamespeed command to lighten the load on slower clients
