Optimize Chunk Unload Queue Removing chunks from the unload queue when performing chunk lookups is a costly activity. It drastically slows down server performance as many methods call getChunkAt, resulting in a bandaid to skip removing chunks from the unload queue. This patch optimizes the unload queue to instead use a boolean on the Chunk object itself to mark if the chunk is active, and then insert into a LinkedList queue. The benefits here is that all chunk unload queue actions are now O(1) constant time. A LinkedList will never need to resize, and can be removed from in constant time when used in a queue like method. We mark the chunk as active in many places that notify it is still being used, so that when the chunk unload queue reaches that chunk, and sees the chunk became active again, it will skip it and move to next.

Subject: [PATCH] Optimize Chunk Unload Queue
Removing chunks from the unload queue when performing chunk lookups is a costly activity.
It drastically slows down server performance as many methods call getChunkAt, resulting in a bandaid
to skip removing chunks from the unload queue.
This patch optimizes the unload queue to instead use a boolean on the Chunk object itself to mark
if the chunk is active, and then insert into a LinkedList queue.
The benefits here is that all chunk unload queue actions are now O(1) constant time.
A LinkedList will never need to resize, and can be removed from in constant time when
used in a queue like method.
We mark the chunk as active in many places that notify it is still being used, so that
when the chunk unload queue reaches that chunk, and sees the chunk became active again,
it will skip it and move to next.
Another attempt at unload queue, including EAR improvements. should be fully working now as I pretty much fell back to existing methods so anything touching the unloadQueue set should behave correctly. And maintained NMS Reflection safe change too

Also optimize EAR to use these methods.

Improve chunk unload queue to maintain some previous expectations While the previous logic was logically correct, some CB API's before would request a chunk without removing it from the unload queue. While this is logically wrong, some plugins seem to be causing unload issues. This change will make anything using that one API that use to not remove from queue, no longer remove from queue. Hopefully other activities on the server will touch the chunk if it REALLY is in use.

Optimize Chunk Unload Queue Removing chunks from the unload queue when performing chunk lookups is a costly activity. It drastically slows down server performance as many methods call getChunkAt, resulting in a bandaid to skip removing chunks from the unload queue. This patch optimizes the unload queue to instead use a boolean on the Chunk object itself to mark if the chunk is active, and then insert into a LinkedList queue. The benefits here is that all chunk unload queue actions are now O(1) constant time. A LinkedList will never need to resize, and can be removed from in constant time when used in a queue like method. We mark the chunk as active in many places that notify it is still being used, so that when the chunk unload queue reaches that chunk, and sees the chunk became active again, it will skip it and move to next.

Improve chunk unload queue to maintain some previous expectations While the previous logic was logically correct, some CB API's before would request a chunk without removing it from the unload queue. While this is logically wrong, some plugins seem to be causing unload issues. This change will make anything using that one API that use to not remove from queue, no longer remove from queue. Hopefully other activities on the server will touch the chunk if it REALLY is in use.
