I was wanting to turn a spare pi3 into an always on minecraft server for my nephew to tinker with (TLDR below)
first step I tried Cuberite, but I had huge complaints from my nephew about combat being flat, AI feeling bad, everything in the region instantly moves towards you in a straight line, core settings like mobgriefing and keepinventory don't exist, spawn point isn't buildable which isn't a minecraft thing, skeletons are super accurate and get stick inside blocks and shoot you from inside! etc
basically a lot of the mechanics just feel really off which is a shame because I was blown away by its performance, world generation took seconds, cpu and ram usage when idle are hardly anything!
switch to minecraft java server, vanilla no mods, people say java is as fast as c++ but initial world generation took minutes, after reboots initial startup takes maybe 60 seconds, its slow to generate new chunks outside of the spawn, its slow to load chunks when exploring and when idle with no users it is eating 60% of the ram and 40% of the cpu !
tldr : I was wondering is anyone was successfully using a pi3 as a MC server ? what are the biggest bottlenecks? any tips or tricks I can do to make it a better experience? (linux stuff or mc settings)
