Subject: [PATCH] Optimise TickListServer by rewriting it
In my profiling TickListServer showed up as
~10% for saving chunks and ~5% for the scheduling
of items on a server with ~90 players at
view distance = 5. Most of the performance
loss is unneccessary.
TickListServer has numerous performance issues:
1. Handling scheduled items is O(nlogn)
2. Getting scheduled items for a chunk is O(n),
with n being the the number of scheduled items
for all chunks (hits saving very hard)
3. Checking if an item is scheduled for the current tick is O(n),
with n being the number of items scheduled for current tick
4. Items not in ticking chunks are churned in the scheduler
The biggest issues are 4 & 2.
We solve 1 by splitting up scheduled items into short and long scheduled,
where we expect the vast majority of our entries to be in the short scheduled
set. Handling short scheduled items is O(n) due to how the comparison
process is reduced to mapping. See TickListServerInterval. However,
this isn't memory-efficient - which is why long scheduled exists.
Long scheduled is handled the same as TickListServer.
2 is solved by mapping what entries are in what chunks.
3 is solved by mapping what blocks have what scheduled for them.
4 is solved by moving the items that are not in ticking chunks
into a map of entries for that chunk. Once the chunk is moved
to ticking, the items are re-scheduled.
This patch has also added two flags to debug excessive tick delays:
-Dpaper.ticklist-warn-on-excessive-delay=true (false by default)
and -Dpaper.ticklist-excessive-delay-threshold=ticks which
sets the excessive tick delay to the specified ticks (defaults to
60 * 20 ticks, aka 60 seconds)
