Server/Requirements/Dedicated

It should be noted that these suggestions presume default settings in server.conf—i.e., a Draw Distance no higher than 10, and are based on a new world. The bigger the world gets, especially if there's advanced redstone circuitry at work, the requirements for large Minecraft Servers and advanced setups—particularly the RAM, or in cases with lots of redstone or mobs (e.g., grinders), the CPU—increase significantly. In fact, a major world with several camps, redstone machinery, grinders, etc., can easily more than double the requirements.

* 1 player ~ 50-100 MB of RAM - on its own, but in practicality, it will always pull more, if it's e.g. in different chunks, moving through chunks very quickly (e.g. on a boat, via rail or flying with elytra); the player object as such won't use/drain more RAM, but it will effectively lead to significantly more RAM being used by the server if it's doing anything besides standing perfectly still somewhere.
