Minecraft Bedrock server RAM: how much do you need?

Bedrock Dedicated Server is a different program from the Java server, written in native code rather than Java, and it needs a fraction of the memory: a vanilla world for a group of friends runs in a gigabyte or two.

Bedrock Dedicated Server is native code, not Java, and spreads world simulation over several threads. tick-distance is the biggest lever on CPU.

What uses the memory in Minecraft Bedrock

There is no Java heap to size, so memory simply follows how much of the world is loaded. That is set by view-distance, the furthest chunks the server will send, and by how spread out your players are. tick-distance controls how much of that loaded area is actually simulated, and it is what drives CPU. Behaviour packs and add-ons add their own entities and scripts on top.

Where people get it wrong

Following Java server advice. Aikar's flags, -Xmx and heap tuning mean nothing to Bedrock, and Java RAM figures overshoot by several times. The setting worth watching is view-distance: the default of 32 chunks is generous, and lowering it saves more than any hardware change.

Rather not run the server yourself?

These tools are free and funded by the two hosting services we run. If you want a server that is already set up, here they are.
