About this project
What does Chunk Sending add?
Optimizes chunk packet sending through sorting and distributing them over time.
- More seamless server login/teleport/respawn/dimension change, as nearby chunks load first
- Less network strain as chunks are spread out over time, decreasing lag spikes and improving playability for people with slow connections
Requires Cupboard dependency to be installed in newer versions

- Configure the maximum amount of chunks sent per tick
No known incompatibilities, should work fine with any mod.
Only required on serverside.
