Aikar 88826e053a Don't sleep between chunk saves 
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.

How To

Download a copy of PaperTools.jar from our buildserver here: https://ci.destroystokyo.com/job/PaperSpigot-BuildTools/

Place PaperTools.jar into an empty directory and run it with java -jar PaperTools.jar from Git-Bash/Bash

It requires you have git installed on your local system as well as JDK 7 or above.

How To (Advanced & Legacy Users)

After running the PaperTools jar, you can compile at any time. A brief overview is provided below. For more novice users, we recommend you avoid these steps and stick to the PaperTools.jar build tool.
