Annuus is a mod for minecraft networking, improves network performance and makes the game more available for running on large server.

Supported minecraft 1.21.x with fabric loader and neoforge loader, needs fabric-api when using fabric.

When the player doesn't install annuus on the client, network packet will send normally like vanilla.

Performance

Chunk data

Deflate 1 has less CPU usage, even though that performance is not good enough here \ So it be considered as a compression option

We have tested view distance as 10 (473), 12 (637), 16 (1057), 32 (3725), installed mod only fabric-api.
