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] Don't blindly send unlit chunks when lighting updates are
|
|
allowed
|
|
|
|
Spigot, by default, disables several mechanisms around how chunks are
|
|
lit, if ever, which has forced them to always send chunks before vanilla
|
|
would consider them ready to send, causing for lots of issues around
|
|
lighting glitches.
|
|
|
|
Shamefully, the amount of work to relight chunks can be detremental
|
|
to some servers, meaning that forcibily disabling light updates can
|
|
cause major performance issues.
|
|
|
|
as such, we make a compromise; if this "feature" is disabled, we will
|
|
only send chunks which are actually ready to be sent, otherwise, we
|
|
will always send chunks.
