Workload inputs

Describe the busy hour.

Use concurrent players, not the advertised slot limit.

Edition

Rule set 1.0.0, reviewed 2026-09-01

Recommended starting range

3-6 GB

Start in the 3-6 GB range, then measure the exact world, server build, and peak concurrency before resizing.

CPU priority

Strong

Prioritize strong sustained single-thread performance and consistent CPU access rather than choosing by total core count alone.

Working storage

20-40 GB working space

Plan for roughly 20-40 GB of working space and monitor world growth; backup copies require capacity outside this range.

Why this result

  • Java Edition with 10 expected simultaneous players selects the baseline; advertised slots are intentionally ignored.
  • Vanilla keeps the software headroom adjustment at the baseline.
  • A new world starts without an existing-world allowance, but its growth still needs monitoring.
  • Moderate exploration adds upper-range and storage headroom for ongoing world generation.
  • A new-server setup avoids import uncertainty; backups should still begin before meaningful play. The selected daily backup need changes the backup plan, not the RAM estimate.
  • Region affects latency and provider choice, not the RAM calculation.

Plan for headroom when

  • Actual simultaneous concurrency consistently exceeds 10; advertised slot capacity is not the same measurement.
  • High view or simulation distance, dense farms or entities, and expensive plugins or mods can increase CPU and memory demand.

Backups and region

Use automatic daily backups plus pre-change snapshots, and keep multiple restore points away from the game server.

A US Central location is a practical first comparison for a North American group spread across coasts; test actual player routes before committing.

Self-host or managed?

Balanced

Either approach can fit: compare the cost and control of self-hosting with the operational support and recovery tooling of a managed host.

Self-host when: Choose self-hosting when you want infrastructure control and can securely operate the network, updates, monitoring, power, availability, and tested off-machine restores.

Choose managed when: Choose managed hosting when predictable availability, support, migration help, and provider-operated backups are worth more than direct infrastructure control; verify each feature rather than assuming it.

This is a HostForge planning estimate, not a guarantee, benchmark, or official Minecraft requirement. Measure the exact server build under realistic peak load and resize when the evidence changes.
