Subject: [PATCH] Performance improvement for Chunk.getEntities
|
|
|
|
This patch aims to reduce performance cost used by collecting the
|
|
entities of a chunk. Previously the entitySlices were copied into an
|
|
extra array with List.toArray() with is a costly and unneccessary
|
|
operation. This patch will reduce the load of plugins which for example
|
|
implement custom moblimits and depend on Chunk.getEntities().
