Reduces number of instructions a chunk lookup does when accessing the last chunk cache. This reduces amount of work and opcodes and allows better inlining. In lots of profiling comparisons, this optimization was able to reduce the cost of repeated chunk lookups that hit the cache pretty significantly.

Subject: [PATCH] Optimize ChunkProviderServer's chunk level checking helper
|
|
methods
|
|
|
|
These can be hot functions (i.e entity ticking and block ticking),
|
|
so inline where possible, and avoid the abstraction of the
|
|
Either class.
