Rule of thumb: 2–4 GB for a few friends, 6–10 GB for a public server with plugins. Set -Xms equal to -Xmx and leave 1–1.5 GB for the operating system. How much RAM?

Upgrading
FAQ
What Java version does Minecraft Snapshot 24w34a need?
Minecraft Snapshot 24w34a needs Java 21 or newer. Running it on an older Java fails with an UnsupportedClassVersionError mentioning class file version 65.0.
Is Minecraft Snapshot 24w34a safe for my survival world?
Only on a copy. Preview versions are experimental and upgrade worlds irreversibly; keep a backup and don't switch a live world to a snapshot, pre-release or release candidate.
Is this the Minecraft game or an APK?
No. This is the Java Edition dedicated server — software for hosting a world. It is not the game client and there is no Android APK. Phone and console players use Bedrock Edition.
