ESU

Please head to This page for the latest and better-formatted description.

A bukkit/velocity plugin that helps manage servers and provide a better gaming environment. Currently in actively developing.

Modern design; Full support of hot loading/unloading or hot updates.
All modules can be enabled and configured independently. (Modules are disabled by default) Modify the configuration or use commands to en/disable modules.
Supports language settings and will provide information based on the client language. You can also set the location of messages (chat, action bar, title) and sounds.
Custom color scheme feature, which allows players to choose their favorite themes! (Still in development)


Module List
ESU-Bukkit

NetworkThrottleModule

• New technique: effectively reduce the upload bandwidth usage by compressing the block data that is invisible to players in the chunk data packet. No impact on non-cheating players. Being deep optimization, the processing time of each chunk is less than 1ms. The load is lower than GrimAC and ore obscure plugins. 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. \

*This feature requires the Spigot/Paper 1.18+.
*This feature conflicts with any Orebfuscator plugin and cannot be installed together. You must use the anti-xray feature from ESU only.
*This feature can still be further enhanced in the future.

• 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.
• Dynamically adjust the view distance of high-latency players to reduce resource usage and improve player experience.
• One of anti-Xray images on gallery:

DO NOT post errors in the spigotmc comments. I don't check it often, which means you will not get support.
