About minecraft-optimization
A GitHub repository hosting a written guide to tuning Minecraft server performance. It explains which server software the author considers reliable (Paper and Purpur are named as top picks, while paid JARs advertising async features, Bukkit/CraftBukkit/Spigot, and runtime plugin loaders are discouraged) and walks through configuration options such as network-compression-threshold in server.properties and use-alternate-keepalive in purpur.yml. It also covers map pregeneration with plugins like Chunky, the need for a world border, and the separate borders required for the overworld, nether and end.
The guide states it is written for version 26.3, and notes that some parts may still apply to 1.15 through 26.2 because it is updated only when something major changes. The author describes it as an aid to understanding which options affect performance rather than a source of perfect results, and says server owners still need to tinker with settings for their own hardware and needs. It includes a note that servers on vanilla, Fabric or Spigot should set sync-chunk-writes to false manually, since Paper and its forks force this setting.

It is written for version 26.3, and the author notes some things may still apply to 1.15 through 26.2.
Do I need to pregenerate my map?
The guide says pregeneration is now only useful on servers with terrible, single-threaded or limited CPUs, though it is commonly used to generate chunks for world-map plugins.
