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.

If you enjoy this mod consider supporting the development, any support is greatly appreciated.

The development is an unpaid free-time activity, so any support helps being able to spend more time on it.
You can support me on Patreon, or just spreading the word around.
