About this Mod
Abstract
https://github.com/Viola-Siemens/Spectrum-Rush/blob/main/README.md
This mod adds a mini-game named Spectrum Rush to Minecraft. When the game starts, n sheep of each of c colors (n*c in total) will be placed around the shared spawn point. Players are asked to collect wool items with corresponding colors within the specified time as many as possible. At the end of the game (operators use the stopping command or all rounds are finished), the player who scores the most wins the game, and a ranking list will be shown to all players.

Server lagging with Spectrum Rush – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Spectrum Rush consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
