Best VPS specs for private voice servers (2–20 users)
Updated: February 2026
Most small groups massively overbuy VPS resources. For private Mumble, good routing and stable CPU matter more than throwing money at RAM.
Quick answer
- 2–5 users: 1 vCPU, 1 GB RAM is usually enough.
- 6–10 users: 1–2 vCPU, 2 GB RAM is a safe baseline.
- 10–20 users: 2 vCPU, 2–4 GB RAM gives breathing room.
Bandwidth usage is usually modest for voice. Latency and jitter hurt more than raw throughput limits.
What actually matters
- CPU consistency: avoid heavily contended bargain nodes.
- Network quality: choose UK/EU region close to your group.
- Firewall clarity: provider firewall + host firewall must match.
- Operational simplicity: smaller, stable setup beats complex cheap stack.
Common buying mistakes
- Buying 8+ GB RAM for a 5-person group.
- Picking cheapest region far from users.
- Ignoring provider firewall and blaming Mumble.
- No monitoring, then guessing during outages.
When to upgrade
- Consistent packet loss or jitter during peak use.
- CPU spikes with multiple services sharing the box.
- Group size outgrows current concurrency assumptions.
Upgrade one step at a time. Don’t jump from tiny to huge without evidence.
Recommended starter profile (most groups)
For 4–10 users: 2 GB RAM, 1–2 vCPU, UK/EU region, clean Ubuntu LTS, strict firewall, weekly snapshot. That’s the boring setup that works.
