This enables us a fast reference to the entities current chunk instead of having to look it up by hashmap lookups. We also store counts by type to further enable other performance optimizations in later patches.

Subject: [PATCH] Improve Maps (in item frames) performance and bug fixes
|
|
|
|
Maps used a modified version of rendering to support plugin controlled
|
|
imaging on maps. The Craft Map Renderer is much slower than Vanilla,
|
|
causing maps in item frames to cause a noticeable hit on server performance.
|
|
|
|
This updates the map system to not use the Craft system if we detect that no
|
|
custom renderers are in use, defaulting to the much simpler Vanilla system.
|
|
|
|
Additionally, numerous issues to player position tracking on maps has been fixed.
