Folia, a fork of Minecraft server software Paper, has implemented a regionalized multithreading system as a solution to player capacity limitations faced by traditional servers. The system allows for better CPU resource utilization and improved performance. A test was conducted to analyze Folia’s performance under various conditions on regular hardware and configurations without using absurdly powerful hardware, which would not be realistic for most use cases. While the server experienced some lag, it ran surprisingly well on consumer-grade hardware with almost 1,000 players. However, further data is required to determine optimal thread allocations and settings.
