Fast Async World Save[Forge/Neo/Fabric] Mod 1.16.5–26.3
MODFast Async World Save is a lightweight server optimization mod that moves world, player, and dimension saving operations off the main server thread. By transferring heavy disk writes to asynchronous background threads, it completely eliminates game-freezing lag spikes during periodic auto-saves.

The mod functions purely on the server side, requires the Cupboard library, and has zero impact on vanilla gameplay mechanics or save data integrity. It delivers consistent server tick rates and smooth multiplayer performance, especially in heavily populated worlds.
