When a chunk is loaded from disk that has already been generated, the server has to promote the chunk through the system to reach it's current desired status level. This results in every single status transition going from the main thread to the world gen threads, only to discover it has no work it actually needs to do.... and then it returns back to main. This back and forth costs a lot of time and can really delay chunk loads when the server is under high TPS due to their being a lot of time in between chunk load times, as well as hogs up the chunk threads from doing actual generation and light work. Additionally, the whole task system uses a lot of CPU on the server threads anyways. So by optimizing status transitions for status's that are already complete, we can run them to the desired level while on main thread (where it has to happen anyways) instead of ever jumping to world gen thread. This will improve chunk loading effeciency to be reduced down to the following scenario / path: 1) MAIN: Chunk Requested, Load Request sent to ChunkTaskManager / IO Queue 2) IO: Once position in queue comes, submit read IO data and schedule to chunk task thread 3) CHUNK: Once IO is loaded and position in queue comes, deserialize the chunk data, process conversions, submit to main queue 4) MAIN: next Chunk Task process (Mid Tick or End Of Tick), load chunk data into world (POI, main thread tasks) 5) MAIN: process status transitions all the way to LIGHT, light schedules Threaded task 6) SERVER: Light tasks register light enablement for chunk and any lighting needing to be done 7) MAIN: Task returns to main, finish processing to FULL/TICKING status Previously would have hopped to SERVER around 12+ times there extra. |
