PaperStream 1.21.11 alpha 1

First public alpha of PaperStream for Minecraft 1.21.11.

NOT OFFICIAL PAPER / not affiliated with PaperMC. Please report problems to PaperStream, not to PaperMC: https://dc.gg/paperstream

Needs Java 21. Replace your server.jar with paperstream-1.21.11-alpha.1.jar, worlds, plugins and configs keep working. Going back to Paper is possible at any time.

This is an alpha: test it on a copy of your server first.

What PaperStream does

• Loads chunks in the direction players look and move first, uses more cores for chunk work
• Chunk workers run below the main thread's CPU priority on Linux, so small servers stay smooth while chunks generate
• Throttles idle mobs and villagers far from players, limits pathfinding per tick
• Slows down redstone clock lag machines, limits piled up armor stands, minecarts, boats and dropped items
• Profiles low, medium and performance (for 2 to 4 cores), /paperstream migrate for servers coming from Paper

Every change has its own switch in paperstream.yml. Full documentation: https://github.com/LucasTHCRR/PaperStream/wiki
