Subject: [PATCH] Optimise recalcBlockCounts() for empty sections
|
|
|
|
In 1.18, every chunk section is initialised to a non-null value
|
|
and recalcBlockCounts() is invoked for each section.
|
|
However, in a standard world, most sections are empty. In such cases,
|
|
recalcBlockCounts() would iterate over ever position - even though
|
|
the block data would all be air. To avoid this, we skip
|
|
searching the section unless the palette indicates there _could_ be
|
|
a non-air block state or non-empty fluid state.
|
|
|
|
Chunk loading initially showed that recalcBlockCounts() over
|
|
sections with a ZeroBitStorage data to to take ~20% of the process,
|
|
now it takes <1%.
