For some unknown reason, Minecraft is sleeping 10ms between every single chunk being saved to disk. Under high chunk load/unload activity (lots of movement / teleporting), this causes the chunk unload queue to build up in size. This has multiple impacts: 1) Performance of the unload queue itself - The save thread is pretty ineffecient for how it accesses it By letting the queue get larger, checking and popping work off the queue can get less performant. 2) Performance of chunk loading - As with #1, chunk loads also have to check this queue when loading chunk data so that it doesn't load stale data if new data is pending write to disk. 3) Memory Usage - The entire chunk has been serialized to NBT, and now sits in this queue. This leads to elevated memory usage, and then the objects used in the serialization sit around longer than needed, resulting in promotion to Old Generation instead of dying young. If there is work to do, then the thread should be doing its work, and only sleep when it is done.

Server randomly hangs after several hours of uptime. I noticed tps randomly dipped to 9 then went back up to 20 before this happened. Heres the only error i see other than one for a deathevent from mobstacker that happened once. http://pastebin.com/raw/CLPgscC8 It says to report to paperspigot so maybe you can guide me in the right direction.
