Subject: [PATCH] Optimize Light Engine
|
|
|
|
Massive update to light to improve performance and chunk loading/generation.
|
|
|
|
1) Massive bit packing/unpacking optimizations and inlining.
|
|
A lot of performance has to do with constant packing and unpacking of bits.
|
|
We now inline a most bit operations, and re-use base x/y/z bits in many places.
|
|
This helps with cpu level processing to just do all the math at once instead
|
|
of having to jump in and out of function calls.
|
|
|
|
This much logic also is likely over the JVM Inline limit for JIT too.
|
|
2) Applied a few of JellySquid's Phosphor mod optimizations such as
|
|
- ensuring we don't notify neighbor chunks when neighbor chunk doesn't need to be notified
|
|
- reduce hasLight checks in initializing light, and prob some more, they are tagged JellySquid where phosphor influence was used.
|
|
3) Optimize hot path accesses to getting updating chunk to have less branching
|
|
4) Optimize getBlock accesses to have less branching, and less unpacking
|
|
5) Have a separate urgent bucket for chunk light tasks. These tasks will always cut in line over non blocking light tasks.
|
|
6) Retain chunk priority while light tasks are enqueued. So if a task comes in at high priority but the queue is full
|
|
of tasks already at a lower priority, before the task was simply added to the end. Now it can cut in line to the front.
|
|
this applies for both urgent and non urgent tasks.
|
|
7) Buffer non urgent tasks even if queueUpdate is called multiple times to improve efficiency.
|
|
8) Fix NPE risk that crashes server in getting nibble data
