Subject: [PATCH] Optimise general POI access
|
|
|
|
There are a couple of problems with mojang's POI code.
|
|
Firstly, it's all streams. Unsurprisingly, stacking
|
|
streams on top of each other is horrible for performance
|
|
and ultimately took up half of a villager's tick!
|
|
|
|
Secondly, sometime's the search radius is large and there are
|
|
a significant number of poi entries per chunk section. Even
|
|
removing streams at this point doesn't help much. The only solution
|
|
is to start at the search point and iterate outwards. This
|
|
type of approach shows massive gains for portals, simply because
|
|
we can avoid sync loading a large area of chunks. I also tested
|
|
a massive farm I found in JellySquid's discord, which showed
|
|
to benefit significantly simply because the farm had so many
|
|
portal blocks that searching through them all was very slow.
|
|
|
|
Great care has been taken so that behavior remains identical to
|
|
vanilla, however I cannot account for oddball Stream API
|
|
implementations, if they even exist (streams can technically
|
|
be loose with iteration order in a sorted stream given its
|
|
source stream is not tagged with ordered, and mojang does not
|
|
tag the source stream as ordered). However in my testing on openjdk
|
|
there showed no difference, as expected.
|
|
|
|
This patch also specifically optimises other areas of code to
|
|
use PoiAccess. For example, some villager AI and portaling code
|
|
had to be specifically modified.
