MC-14946Performance on horses is broken
When riding a horse, you may usually get your horse stopped for a second, then it gets you to where it really was. I don't know if this is because new chunks are loading, or just server lag. I think this is a bug, confirm it as soon as possible please.
The reason this happens is because the Java server code runs world generation and world simulation on the same thread. It means that when it creates new parts of the world, everything in the world stops. You don't usually notice this, because players can update themselves, but when you are on a horse you are bound to the horse's update.
We do not have a fix for this at the moment. It requires a large rewrite, which may happen at a later time.
