Self-Hosting a Minecraft Server: RAM, CPU and DDoS
Spinning up your own Minecraft server sounds easy — until 20 players load chunks at once and the TPS collapse. This guide shows how much RAM and CPU you need per player count, why DDoS attacks on game servers are real, and when self-hosting beats a ready-made rented Minecraft server .
Rent a Minecraft serverA Minecraft server's performance hinges on two things: the single-core performance of the CPU and the available RAM. A vanilla server is frugal; a modded server with a big modpack can struggle to serve the same player count. Know the rules of thumb and you size it right from the start — instead of fighting lag later.
RAM and CPU by player count
The figures below are practical rules of thumb, not measured benchmarks. They apply to vanilla and lightly modded servers; large modpacks, many plugins or a high view distance push the requirements up noticeably.
| Players | Recommended RAM | CPU / vCPU | Tier |
|---|---|---|---|
| 1–5 (vanilla) | 2–3 GB | 1–2 fast cores | Small |
| 5–10 | 4 GB | 2 cores | Small–medium |
| 10–20 | 6–8 GB | 2–4 cores | Medium |
| 20–40 | 8–12 GB | 4+ cores | Large |
| Modpacks (10–20 players) | 8–16 GB | 4+ fast cores | Resource-hungry |
Why single-thread CPU performance matters
Minecraft's server tick is fundamentally single-threaded. Server forks like Paper or Spigot offload some work, but the main load stays pinned to one thread. That's why a CPU with high single-core clocks beats many slow cores. And this is exactly where an overbooked host bites: shared vCPUs and overprovisioning cause TPS drops the moment your neighbours generate load.
The DDoS reality for game servers
Minecraft servers are a favourite target for DDoS attacks — from griefers, competitors or simply out of boredom. An unprotected home line or a cheap VPS with no protection goes offline with a single attack, and every player with it. Always-on DDoS protection is therefore not a nice-to-have but baseline kit for any public server.
Latency and the Frankfurt location
For PvP and a smooth feel, low ping is what counts. A server in Frankfurt offers short paths to players across the DACH region and the EU. Hosting at home, by contrast, means limited upload, usually a dynamic IP, and your private connection becoming publicly visible — not a good starting point for a growing server.
Self-host or rent?
- Host at home: full control, but limited upload, dynamic IP, your home IP is exposed, no DDoS protection — power and uptime are on you.
- On your own cloud server: static IP, solid uplink, DDoS protection , full root control — you administer it yourself.
- Fully rented: fastest start, least effort — a rented Minecraft server handles setup and protection for you.
