Lol, ok, I'll bite, what are your upload/ download speeds? Also I'm curious as to what kind of CPU you're running the server off of, RAM isn't everything. And I'm pretty sure EVERYONE gets that kind of lag when they get randomly teleported +1 million blocks, that's all server side stuff as far as generating new chunks and such goes. By the way, the amount of RAM you have isn't going to affect how quickly the server can generate and load new chunks or the speed at which it can send new data to clients.
