[This happens whether spigot or bukkit latest build] This has to be an issue with spigot. I have tried removing all plugins but multiverse, and even tried swapping out multiverse with another multiworld plugin. Completely barebones. If I try to single handedly (No other players) teleport to a world, the whole entire server completely hangs up for 10-15 seconds as the chunks load. No one can chat, no one can execute commands. After all chunks in the area have loaded, the server continues. I am using Java 7 with a 1270v2, 32gb ram, 1GB/s line @ 30TB bandwidth, and 120gb SSD. There should be NO reason that this is my server. Here are example timings, looks to be no issues here: http://aikar.co/timings.php?url=5571437/ So it has to be spigot, barebones it still happens. This is a terrible bug that needs to be fixed as soon as possible. It is game breaking in many aspects.
