ZstdMC

ZstdMC: Multiplayer Network Optimization
ZstdMC is a performance-focused mod designed to optimize network bandwidth usage in multiplayer environments.

By replacing Minecraft’s built-in compression and decompression modules with the Zstandard (zstd) library, this mod achieves significantly higher compression ratios, resulting in substantial data savings. In most scenarios, it provides these benefits with no negative impact on the game’s stability or performance.

Key Features
Bandwidth Efficiency: Saves approximately 40% to 90% of network traffic in multiplayer mode.

Low Overhead: High-performance compression that minimizes CPU resource consumption.

Easy Setup: Simply drop the mod file into both the server and client mods folders.

Configuration Requirement
To enable the optimization, ensure your server’s server.properties file has the following parameter set:

network-compression-threshold=128 (or higher)

Important Note on Versions
