I covered a lot of minecraft servers on the Pi becasue it was just something to do. Then people kept asking what Pi should they buy for a Minecraft server. Well, the asnwer is none. The Pi is a tinker board, not a server. Not any type of server. Especially a game server which requires far more resources than a simple web server.
My advice has always been to buy a cheap x86 eBay PC. There's only around 4 game servers which can be run on the Pi, so what's the point? For the same price you can buy an old workstation PC with a CPU that's at least twice as powerful as the Pi. More games, more power, why buy a Pi?
People never listen so I stopped making Pi videos and started making these, to prove a point. The only benefit a Pi has is portability and low power. Neither of which are good for a server.
These videos cover performance for both the Java and Bedrock editions. Java does not have a setup guide as it's exactly the same as the Pi and I, along with others, have covered many times before. The Bedrock server I'm running has a setup guide as it's using the official Bedrock server and have never been able to run one of these before. It's not available on ARM architecture!
Spoiler, the official Bedrock edition server massively outperforms the Java edition server
