Minestom VS Paper

- What server software or framework to use. Ideally, if you dont need too much vanilla features (world generation, all mobs & items implemented, etc), I'd use something lightweight that is not based off of the vanilla server software. There are a few projects like this on github, including: https://github.com/Minestom/Minestom , https://github.com/feather-rs/feather , https://github.com/KryptonMC/Krypton , https://github.com/df-mc/dragonfly (bedrock). Which one you use will probably depend mostly on your preference. - You will need a way to store data separate from the servers. A database like postgres should work. There are a lot of different databases tho!

Even if performance is your worry, Minestom is an open-source barebones reimplementation of the minecraft server. With this, you can make extremelly custom things and let people connect using the default vanilla client. Of coruse, you can pair this with a mod if you want to.

Depends on what you're doing on said server. If it doesn't require vanilla mechanics then Minestom might suit the job well. Other than that, I'd recommend Paper, Purpur or Pufferfish.

It's unlikely to achieve have such performance and feature using Paper/Bukkit/Spigot or the one provided by Mojang. If you want to write your own server-side software, you could use Minestom.

This is quite a difficult questions because it depends on which type of Minecraft is currently being used (java, bedrock, education). The hardware available for the server as well as the ages of the students. Normal Minecraft servers are notoriously single threaded which makes it hard to host a server for 75 without good hardware. You could look into a project called minestom which is a nice library for making a multi threaded server, but it would require the students to program the server themselves. Which definitely could be fun and educational, but isn't doable with younger students

It is called Minestom. Its not done, but here is the website and discord. If you check out the showcase channel in the discord you'll see some pretty cool stuff they've made with the current program.

Im experimenting with Minestom and I want to make some crazy stress tests (1k users).

Also to add to this, if you don't need full vanilla functionality and are more focus on higher player count than something slightly more experimental but more performant might be your best bet like GlowstoneMC (glowstone supports paper plugins) or Minestrom

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
