Speed up processing of chunk loads and generation Credit to Spotted for the idea A lot of the new chunk system requires constant back and forth the main thread to handle priority scheduling and ensuring conflicting tasks do not run at the same time. The issue is, these queues are only checked at either: A) Sync Chunk Loads B) End of Tick while sleeping This results in generating chunks sitting waiting for a full tick to complete before it will even start the next unit of work to do. Additionally, this also delays loading of chunks until this same timing. We will now periodically poll the chunk task queues throughout the tick, looking for work to do. We do this in a fair method that considers all worlds, not just the one being ticked, so that each world can get 1 task procesed each before the next pass. We also cap the throughput of these task processes to 1 per world per 0.1ms or 200 max per tick, to ensure that high volume of tasks do not overload the current tick time. In a view distance of 15, chunk loading performance was visually faster on the client. Flying at high speed in spectator mode was able to keep up with chunk loading (as long as they are already generated)

Improve mid tick chunk loading, Fix Oversleep, other improvements Process loads outside of any canSleep check. Original intent was to only apply those restrictions to generations but realized I had some checks higher up the call chain. Reworked the back off strategy to just run every 1 millisecond per world, and to apply the per tick limit to generations only. This guarantees that your chunk will load with at most around 1ms delay. Additionally, fire midTick processing in a few more places, notably the oversleep section so we can keep processing loads here too which has a large up to 50ms window... Speaking of oversleep, we had a bug in our implementation changes for Timings that caused oversleep to not sleep the correct amount. Because we now moved it into the NEXT tick instead of THIS tick, the value of nextTick had already been increased to +50ms, resulting in the risk of sleeping more than it should, but, more importantly, this caused every task that was trying to NOT run during oversleep to actually run during oversleep. This is now fixed. Another small tweak is to the /tps command, to no longer show the star when TPS is right at 20. Due to ineffeciencies in the sleep precision, TPS is commonly 20.02. This causes the star to show up almost constantly, so now only show it if we actually hit a real "catchup". This commit also improves the changes to the CallbackExecutor, in that it now is also recursion safe. It was possible that the executor could run tasks out of desired order if the executor task scheduled more executor tasks. We solve this by ensuring new additions do not enter the currently iterated queue. Each depth level will have its own queue. Fixes #3220

A lot of the new chunk system requires constant back and forth the main thread
to handle priority scheduling and ensuring conflicting tasks do not run at the
same time.
The issue is, these queues are only checked at either:
A) Sync Chunk Loads
B) End of Tick while sleeping
This results in generating chunks sitting waiting for a full tick to
complete before it will even start the next unit of work to do.
Additionally, this also delays loading of chunks until this same timing.
We will now periodically poll the chunk task queues throughout the tick,
looking for work to do.
We do this in a fair method that considers all worlds, not just the one being
ticked, so that each world can get 1 task procesed each before the next pass.
In a view distance of 15, chunk loading performance was visually faster on the client.

(FIRST 1.16.3): Update Paper to 1.16.3 This is a pretty tiny update with very little changed. Recommended to update from 1.16.2 ASAP as 1.16.2 is now no longer supported. Plugins should mostly remain working as the NMS revision did not change.

1.16.2 Release (#4123) PaperMC believes that 1.16.2 is now ready for general release as we fixed the main issue plagueing the 1.16.x release, the MapLike data conversion issues. Until now, it was not safe for a server to convert a world to 1.16.2 without data conversion issues around villages and potentially other things. If you did, those MapLike errors meant something went wrong. This is now resolved. Big thanks to all those that helped, notably @BillyGalbreath and @Proximyst who did large parts of the update process with me. Please as always, backup your worlds and test before updating to 1.16.2!

Speed up processing of chunk loads and generation Credit to Spotted for the idea A lot of the new chunk system requires constant back and forth the main thread to handle priority scheduling and ensuring conflicting tasks do not run at the same time. The issue is, these queues are only checked at either: A) Sync Chunk Loads B) End of Tick while sleeping This results in generating chunks sitting waiting for a full tick to complete before it will even start the next unit of work to do. Additionally, this also delays loading of chunks until this same timing. We will now periodically poll the chunk task queues throughout the tick, looking for work to do. We do this in a fair method that considers all worlds, not just the one being ticked, so that each world can get 1 task procesed each before the next pass. We also cap the throughput of these task processes to 1 per world per 0.1ms or 200 max per tick, to ensure that high volume of tasks do not overload the current tick time. In a view distance of 15, chunk loading performance was visually faster on the client. Flying at high speed in spectator mode was able to keep up with chunk loading (as long as they are already generated)

1.16.2 Release (#4123) PaperMC believes that 1.16.2 is now ready for general release as we fixed the main issue plagueing the 1.16.x release, the MapLike data conversion issues. Until now, it was not safe for a server to convert a world to 1.16.2 without data conversion issues around villages and potentially other things. If you did, those MapLike errors meant something went wrong. This is now resolved.

Improve mid tick chunk loading, Fix Oversleep, other improvements Process loads outside of any canSleep check. Original intent was to only apply those restrictions to generations but realized I had some checks higher up the call chain. Reworked the back off strategy to just run every 1 millisecond per world, and to apply the per tick limit to generations only. This guarantees that your chunk will load with at most around 1ms delay. Additionally, fire midTick processing in a few more places, notably the oversleep section so we can keep processing loads here too which has a large up to 50ms window... Speaking of oversleep, we had a bug in our implementation changes for Timings that caused oversleep to not sleep the correct amount. Because we now moved it into the NEXT tick instead of THIS tick, the value of nextTick had already been increased to +50ms, resulting in the risk of sleeping more than it should, but, more importantly, this caused every task that was trying to NOT run during oversleep to actually run during oversleep. This is now fixed. Another small tweak is to the /tps command, to no longer show the star when TPS is right at 20. Due to ineffeciencies in the sleep precision, TPS is commonly 20.02. This causes the star to show up almost constantly, so now only show it if we actually hit a real "catchup". This commit also improves the changes to the CallbackExecutor, in that it now is also recursion safe. It was possible that the executor could run tasks out of desired order if the executor task scheduled more executor tasks. We solve this by ensuring new additions do not enter the currently iterated queue. Each depth level will have its own queue. Fixes #3220

Implement Chunk Priority / Urgency System for Chunks Mark chunks that are blocking main thread for world generation as urgent Implements a general priority system so that chunks that are sorted in the generator queues can prioritize certain chunks over another. Urgent chunks will jump to the front of the line, ensuring that a sync chunk load on an ungenerated chunk does not lag the server for a long period of time if the servers generator queues are filled with lots of chunks already. This massively reduces the lag spikes from sync chunk gens. Then we further prioritize loading order so nearby chunks have higher priority than distant chunks, reducing the pressure a high no tick view distance holds on you. Chunks in front of the player have higher priority, to help with fast traveling players keep up with their movement. This commit also improves single core cpu scenarios in that we will now automatically disable Async Chunks as well as Minecrafts thread pool. It is never recommended to use async chunks on a single CPU as context switching will be slower than just running it all on main. This also bumps the number of server worker threads by default too. Mojang does not utilize the workers in an effecient manner, resulting in them using barely any sustained CPU. So give it more workers so more chunks can be processed concurrently This change also improves urgent chunk loading, so players flying into unloaded chunks will hurt a little bit less (but still hurt) Ping #3395 #3363 (Not marking as closed, we need to make prevent moving work)

Speed up processing of chunk loads and generation Credit to Spotted for the idea A lot of the new chunk system requires constant back and forth the main thread to handle priority scheduling and ensuring conflicting tasks do not run at the same time. The issue is, these queues are only checked at either: A) Sync Chunk Loads B) End of Tick while sleeping This results in generating chunks sitting waiting for a full tick to complete before it will even start the next unit of work to do. Additionally, this also delays loading of chunks until this same timing. We will now periodically poll the chunk task queues throughout the tick, looking for work to do. We do this in a fair method that considers all worlds, not just the one being ticked, so that each world can get 1 task procesed each before the next pass. We also cap the throughput of these task processes to 1 per world per 0.1ms or 200 max per tick, to ensure that high volume of tasks do not overload the current tick time. In a view distance of 15, chunk loading performance was visually faster on the client. Flying at high speed in spectator mode was able to keep up with chunk loading (as long as they are already generated)

Fix undesirable behavior around world level changes due to priority priority tickets being added at 33 was hurting sync EMPTY and lesser requests. this was likely the source of recent treasure map issues. This then further hurt nether portal travel too. lots of oddness around. This also avoids scheduling a level change on ticket removal when the level is unchanged, as well as ditches CB's horrible change to not letting you access an unloading chunk which should be valid to cancel the unload

Improve mid tick chunk loading, Fix Oversleep, other improvements Process loads outside of any canSleep check. Original intent was to only apply those restrictions to generations but realized I had some checks higher up the call chain. Reworked the back off strategy to just run every 1 millisecond per world, and to apply the per tick limit to generations only. This guarantees that your chunk will load with at most around 1ms delay. Additionally, fire midTick processing in a few more places, notably the oversleep section so we can keep processing loads here too which has a large up to 50ms window... Speaking of oversleep, we had a bug in our implementation changes for Timings that caused oversleep to not sleep the correct amount. Because we now moved it into the NEXT tick instead of THIS tick, the value of nextTick had already been increased to +50ms, resulting in the risk of sleeping more than it should, but, more importantly, this caused every task that was trying to NOT run during oversleep to actually run during oversleep. This is now fixed. Another small tweak is to the /tps command, to no longer show the star when TPS is right at 20. Due to ineffeciencies in the sleep precision, TPS is commonly 20.02. This causes the star to show up almost constantly, so now only show it if we actually hit a real "catchup". This commit also improves the changes to the CallbackExecutor, in that it now is also recursion safe. It was possible that the executor could run tasks out of desired order if the executor task scheduled more executor tasks. We solve this by ensuring new additions do not enter the currently iterated queue. Each depth level will have its own queue. Fixes #3220

Speed up processing of chunk loads and generation Credit to Spotted for the idea A lot of the new chunk system requires constant back and forth the main thread to handle priority scheduling and ensuring conflicting tasks do not run at the same time. The issue is, these queues are only checked at either: A) Sync Chunk Loads B) End of Tick while sleeping This results in generating chunks sitting waiting for a full tick to complete before it will even start the next unit of work to do. Additionally, this also delays loading of chunks until this same timing. We will now periodically poll the chunk task queues throughout the tick, looking for work to do. We do this in a fair method that considers all worlds, not just the one being ticked, so that each world can get 1 task procesed each before the next pass. We also cap the throughput of these task processes to 1 per world per 0.1ms or 200 max per tick, to ensure that high volume of tasks do not overload the current tick time. In a view distance of 15, chunk loading performance was visually faster on the client. Flying at high speed in spectator mode was able to keep up with chunk loading (as long as they are already generated)
