Server/Requirements/Dedicated

It should be noted that these suggestion presume default settings in server.conf - i.e., a Draw Distance no higher than 10, and is also based on a new world; the bigger the world gets, especially if there's advanced redstone circuitry at work, the requirements - especially the RAM, or in the case of lots of redstone or mobs (in e.g. grinders), the CPU - increase significantly (to the point where a major world with several camps, redstone machinery, grinders, etcetera 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.
