Pufferfish Minecraft Server Software (1.21.3, 1.20.1) is a fork of PaperMC (PaperMC is a fork of Spigot, built from CraftBukkit). It was developed with the goal of improving performance compared to PaperMC and Purpur (another fork of Paper). Pufferfish focuses on enhancing server performance, making it suitable for servers that need to handle a large number of players (Dozens or hundreds of players) or heavy mods/plugins.

Features:

  • Async Entity Tracking: Tracks entities (such as mobs, players, or items) on a separate thread, reducing the load on the main thread and improving server performance.
  • Async Pathfinding: Optimizes the pathfinding algorithm for mobs, enabling faster processing and reducing lag.
  • Entity Performance Optimization: Reduces the performance impact of entities by eliminating unnecessary tasks.
  • Faster Map Rendering: Reduces or eliminates lag spikes when using plugins like ImageOnMap or ImageMaps due to map rendering that is up to 8 times faster.
  • Sentry Integration: Supports detailed error tracking, making it easier for administrators to detect and resolve issues.
  • PaperMC Compatibility: Pufferfish supports all PaperMC plugins, allowing an easy transition from Paper to Pufferfish without needing to change plugin configurations.

Pufferfish+

  • Pufferfish+ provides additional optimizations such as async entity tracking and advanced pathfinding, improving performance by 30-40% compared to standard Pufferfish. It is designed for “enterprise” servers with a large number of players or high performance requirements.
