About Fast Chunk Pregenerator
From SpigotMCGenerate chunks | Sync/Async | Pregen filter for high performance
This plugin can be used to pregenerate as many chunks on as many worlds as you want.
It supports async chunk calls for Paper to maximize generation speed.
You can restart your server at any time, cancel pending tasks and add more worlds whenever you want.
You got full control over how much CPU time the generation should reserve.
Either generate chunks slow in the background with minimal performance impact. Or try to force as many chunk loads as possible in order to pregenerate your world at higher speeds.
generate chunks faster than other chunk generation plugins
as they normally check chunk generations while generating.
