Module List

ESU-Bukkit

NetworkThrottleModule

• ChunkDataThrottle: Effectively reduce the upload bandwidth usage by compressing the block data that is invisible to players in the chunk data packet. Being deep optimization, the processing time of each chunk is up to 0.3ms. The load is extremely low that you don't need to worry about.
  Runing an 200-player vanilla survival server in months, this function helped reduce the upload bandwidth by about 50% (compared with vanilla). For detailed instructions, please check the comments in the module configuration.
  While ensuring maximum compression and high performance, providing Anti-Xray.
  *This feature requires Spigot/Paper 1.18+.
  *This feature conflicts with any other Orebfuscators and cannot be used with together. You must use the anti-xray feature from ESU only.
• AfkEfficiency: Reduce packets send to afk players. Could save a lot of bandwidth from mob farms.
• EntityCulling: Hide entities behind the walls to save your bandwidth - or you can use as anti-esp. Highly optimized too, really low resource draw. Requires Paper 1.19+ .
• DynamicChunkSendRate: Cooperate with the Velocity plugin to monitor real-time bandwidth information and dynamically adjust the chunk sending/reading rate for players according to bandwidth usage. Helps with bandwidth spikes and evenly distribute bandwidth usage.
• HighLatencyAdjust: Dynamically adjust the view distance of high-latency players to reduce resource usage and improve player experience.
