Paper VS cuberite

We will be downloading the Minecraft server files into this directory. To preface, there are numerous variations of server JARs that can be used (e.g. Spigot, Paper, Purpur each touting their own benefits). For this tutorial, we will be working with Paper, a fork of Spigot that is optimized for performance.

PaperMC, a minecraft server has over a quarter million lines of code Github link

Paper fixed it here: https://github.com/PaperMC/Paper/commit/8493340be4fa69fa9369719272e5dff1b7a2f455

Go to papermc.io and download Waterfall or Velocity

This is actually a known issue which was mostly ignored: https://github.com/PaperMC/Paper/issues/3110

You might be able to port a C/C++ implementation to Arduino or another language with a good ESP compiler, but that's going to be a lot of effort, and the biggest challenge you're going to face isn't RAM, it's disk space--Minecraft worlds can be GB in size, so you'll need to pair your microcontroller with, say, an SD card reader and then adapt a whole disk IO system

Shout out for Cuberite as an alternative Minecraft server project that desperately needs more volunteers

https://github.com/cuberite/cuberite

"Cuberite is a Minecraft-compatible multiplayer game server that is written in C++ and designed to be efficient with memory and CPU"

Cuberite has been demoed running on old ARM Android phones and hosting multiple players off it at once. Its performance absolutely annihilates the Java based 'vanilla' server

so basically Cuberite but more officially and with a rewritten client as well

Some have started doing this already, like Cuberite and McPy.

For minecraft server I guess it is worth trying this out: https://github.com/cuberite/cuberite

For the server you should look into Cuberite, same thing but for the server and written in C++.

There were a bunch of attempts in the past. Cuberite is still actively maintained but I have never tried them: https://github.com/cuberite/cuberite
