Reduces bandwidth in your Minecraft server by various modules, decreasing lag due to limited bandwidth and enchants experience.
BandwidthReducer is a comprehensive Minecraft server optimization plugin that reduces unnecessary network traffic while keeping the player experience smooth.
It focuses on optimizing entity updates, AFK player behavior, packet redundancy, and simulating packet compression for advanced bandwidth reduction.
The plugin is highly configurable, compatible with Paper/Spigot servers, and works silently in the background.
Mob AI Optimization
Randomly disables mob AI for distant mobs to reduce network updates.
Keeps nearby mobs fully functional to preserve gameplay experience.
Configurable reduction percentage (40–60% recommended for survival servers).
Dectects "farms" and cancel part of entity packets (will not be visible to player).
AFK Player World Freezer
Detects idle (AFK) players.
Freezes nearby entities, blocks, and weather updates around AFK players to reduce server workload.
Configurable AFK timeout and freeze radius.
Packet Cleaner
Intercepts unnecessary packets, such as interactions with air or non-interactable blocks.
Simulates saved bandwidth per player action.
Packet Compressor
Compresses various outgoing packets including:
Chat, titles, action bars
Entity metadata and teleportation
Player info and position updates
Chunk and block updates
Optional: particles, sounds, maps
⚠️Warning: High CPU usage when aggressively compressing packets; 60% compression recommended for most servers.
Highly configurable: fine-tune each module to suit your server.
Reduces network usage on large survival servers with many players or mobs.
Improves server responsiveness and smoothness under heavy load.
Compatible with Paper/Spigot without requiring mods.
Runs silently in the background.
Place BandwidthReducer.jar in your plugins folder.
Install ProtocolLib: https://www.spigotmc.org/resources/protocollib.1997/
Restart the server.
Edit config.yml to enable/disable modules and adjust parameters:
mob-ai.reduction-percent → percentage of mobs to disable AI
afk-freeze.afk-seconds → AFK timeout
afk-freeze.radius → freeze radius around AFK players
packet-compress.* → toggle packet types for compression
packet-cleaner.reduction-percent → percentage of packet reduction
Mob AI optimization heavily affects server view updates; 40–60% recommended.
Packet compression is CPU-intensive; use cautiously.
/br function enable/disable
Enable or disable a specific optimization module
Modules: mob-ai, packet-compress, afk-reduce, packet-cleaner
/br reload
Reload the plugin configuration without restarting the server
Designed for large-scale survival servers with many entities and players.
Focuses purely on bandwidth optimization; CPU usage is minimal unless modules are aggressively configured.
Simulated compression is not lossless network compression; it aims to reduce redundant data sent.
This plugin does not fix packet loss or network lag caused by external issues.
It is currently tested on Paper, Spigot, and Bukkit servers.
Folia support may come in a future major version (v2.0).
