It seems as if the new generation method is a heavily single threaded work load. If they can find a way to split the load across the threads it would be significantly faster.
@Digit1704 It is a major issue. The fact that the newest snapshot is better than the last coupled with the fact this ticket has yet to move past the open stage tells me the chunk gen code is still being actively altered. If my observation is correct they could be intending to finish all the new features and changes to chunk gen/loading before optimizing the code. It would be nice if @Mojang would communicate with us a little better on major bugs like this one though.
Can confirm 18w50a is atleast playable however moving long distances is a great test of patience.
@David Chamberlin Yeah. SMP Is unplayable right now. Hopefully they fix this soon.
Update: One core of the server CPU is pinned at all times. while the others idle around 15% Then minutes later it will be a different core that is pinned.
@Vicente I was in the same boat as you for a bit however if you read back in the comments you can see the issue is more dramatic when the number of chunks you are loading at anyone time is less than the amount the server has loaded. When I say more dramatic I mean while loading only a few chunks the game is unplayable and at a higher amount of chunks it runs just fine and is playable. Mind you your PC does have to be good enough to render larger amounts of chunks but it does effectively solve the problem. I think the main reason this issue is so bad for some people is because the temporary solution is counter intuitive requiring you to load more chunks client side instead of less.
