Changelog
- Update to 1.21.9
- Rewrite chunk system scheduling so that tasks are balanced based on load and not by queue. This improves scheduling by not biasing worlds with lower numbers of players
- Improve efficiency of the now heavily used ticket counter system
- Remove parallel generation config option as it is no longer supported with the new chunk system scheduling
- Improve thread locality of Starlight propagator cache
- Reduce maximum memory usage of Starlight propagator
- Add new /moonrise tps command
- Rewrite server tick loop to achieve lower perceived packet latency
- Add config option for maximum number of ticks to catch up on, which by default is set to lower impacts from lagspikes
