Quick answer: A vanilla Minecraft server for 10 players needs 6-8 GB RAM, a CPU with 3.5 GHz+ single-core speed, and NVMe SSD storage. For modded servers, double that. Here's exactly what to get and why.
Requirements at a glance
| Component | Minimum (10 players) | Recommended (10 players) | Modded (10 players) |
|---|---|---|---|
| RAM | 4 GB | 6-8 GB | 10-16 GB |
| CPU clock speed | 3.0 GHz | 3.5 GHz+ | 3.8 GHz+ |
| CPU cores | 2 | 4 | 4-6 |
| Storage type | HDD (slow) | NVMe SSD | NVMe SSD |
| Storage space | 10 GB | 20 GB | 40-80 GB |
| Network upload | 10 Mbps | 25 Mbps | 25 Mbps |
| OS | Ubuntu 22.04 LTS | Ubuntu 22.04 LTS | Ubuntu 22.04 LTS |
| Java version | Java 21 | Java 21 | Java 21 |
RAM: what you actually need for 10 players
6-8 GB is the sweet spot. Here's how that breaks down:
- Minecraft server base process: ~1.5-2 GB
- Per active player (chunk loading, entity tracking): ~200-300 MB each x 10 = ~2-3 GB
- World data, spawn chunks, map cache: ~1-2 GB
- OS overhead: ~512 MB-1 GB
- Buffer (don't fully saturate RAM): ~500 MB
That adds up to roughly 5.5-8.5 GB under real load. 6 GB is viable but tight, 8 GB is comfortable and gives you room to grow.
RAM by server type for 10 players
| Server type | RAM needed | Notes |
|---|---|---|
| Vanilla 1.21 | 6 GB | Stable, low overhead |
| Paper / Purpur | 6 GB | Slightly more efficient than vanilla |
| Spigot with plugins (10-20 plugins) | 6-8 GB | Depends heavily on plugin quality |
| Forge / NeoForge (small modpack) | 8-10 GB | 50-100 mods |
| ATM10 / large kitchen-sink pack | 12-16 GB | 400-500 mods, non-negotiable |
| RLCraft | 8-10 GB | Entity-heavy, needs extra headroom |
Don't over-allocate. Giving a 10-player vanilla server 16 GB does not make it faster. Java's garbage collector then has to sweep a larger heap, which causes periodic freeze spikes. Allocate what you need plus a 20% buffer, not everything you have.
CPU: single-core speed matters more than core count
Minecraft's game loop runs on a single thread. That means a 4.5 GHz dual-core CPU will outperform a 3.0 GHz 8-core CPU for tick processing.
For 10 players, you want:
- 3.5 GHz+ single-core boost clock
- 4 cores minimum (other cores handle I/O, plugins, async tasks)
- Modern architecture (AMD Ryzen 5000 / 7000 series or Intel 12th gen+)
CPU performance comparison for Minecraft hosting
| CPU | Single-core clock | Good for 10 players? | Notes |
|---|---|---|---|
| AMD Ryzen 9 9950X | 5.7 GHz boost | Excellent | Overkill for 10 players, great for 50+ |
| AMD Ryzen 9 7950X | 5.7 GHz boost | Excellent | Common in dedicated game hosting |
| AMD Ryzen 5 5600X | 4.6 GHz boost | Very good | Cost-effective sweet spot |
| Intel Core i7-13700K | 5.4 GHz boost | Excellent | Strong single-core for tick speed |
| Intel Xeon E5-2678 v3 | 3.1 GHz | Marginal | Old server CPUs underperform here |
| ARM (Oracle Always Free) | ~2.4 GHz | Not recommended | Low clock, noticeably laggier |
The Xeon / ARM row is worth noting: many "free" or cheap VPS offers run old multi-core Xeon or ARM chips with low single-core clocks. These feel fine at 2-3 players and fall apart at 10.
Storage: NVMe makes a real difference at 10 players
At 10 players simultaneously exploring and loading chunks, storage I/O becomes a genuine bottleneck if you're on a spinning HDD.
- HDD: chunk loading delays of 1-3 seconds when players move to new areas, noticeable rubberbanding on world edges
- SATA SSD: much better, chunks load in ~300ms
- NVMe SSD: chunks load in under 100ms, essentially imperceptible
For 10 players, use NVMe SSD. SATA SSD is acceptable. HDD causes real problems.
Storage space needed for 10 players
| World type | Storage estimate (6 months) | Notes |
|---|---|---|
| Vanilla, casual exploration | 5-15 GB | Grows with explored area |
| Vanilla, heavy exploration | 20-40 GB | Players spread across many chunks |
| Modded (small pack) | 15-30 GB | Extra mod assets, configs |
| Modded (large pack like ATM10) | 40-80 GB | Pack files alone are 5-10 GB |
Network: upload speed is the one that matters
You need upload speed, not download. Each player receives a stream of packets from your server. For 10 players:
- Typical requirement: 5-10 Mbps sustained upload
- Recommended: 25 Mbps (gives headroom for spikes during mass chunk loading)
- Ping matters: sub-50ms to most players for smooth gameplay. European players on a US server will feel it.
For 10 European players, host in Amsterdam, Frankfurt, or London. For North American players, host in New York or Dallas.
Java version: use Java 21, nothing older
Minecraft 1.20.5+ requires Java 21. Java 17 will not run recent versions. Java 8 is years out of date and should not be used for anything current.
Java 21 also introduced significant garbage collection improvements (specifically the G1GC tuning) that reduce lag spikes on servers with 4+ GB heap. This is a real performance difference, not just a version formality.
Recommended JVM flags for a 10-player server
Copy these startup flags. They're tuned for 6-8 GB RAM, 10 players, vanilla or lightly modded:
java -Xms4G -Xmx6G \
-XX:+UseG1GC \
-XX:+ParallelRefProcEnabled \
-XX:MaxGCPauseMillis=200 \
-XX:+UnlockExperimentalVMOptions \
-XX:+DisableExplicitGC \
-XX:+AlwaysPreTouch \
-XX:G1NewSizePercent=30 \
-XX:G1MaxNewSizePercent=40 \
-XX:G1HeapRegionSize=8M \
-XX:G1ReservePercent=20 \
-XX:G1HeapWastePercent=5 \
-XX:G1MixedGCCountTarget=4 \
-XX:InitiatingHeapOccupancyPercent=15 \
-XX:G1MixedGCLiveThresholdPercent=90 \
-XX:G1RSetUpdatingPauseTimePercent=5 \
-XX:SurvivorRatio=32 \
-XX:+PerfDisableSharedMem \
-XX:MaxTenuringThreshold=1 \
-jar server.jar nogui
Change -Xms4G -Xmx6G to match your actual RAM allocation. Keep -Xms and -Xmx equal if you want to pre-allocate memory on startup (slightly reduces GC overhead on long-running servers).
Self-hosting vs. hosted server for 10 players
| Option | Cost | Effort | Performance |
|---|---|---|---|
| Your gaming PC | Free | High (always-on, port forwarding, maintenance) | Depends on your hardware |
| Budget shared hosting | €3-8/mo | Low | Often undersized or oversold CPU |
| Game server hosting (Space-Node) | €8-15/mo | Very low | Dedicated resources, NVMe, Ryzen 9 |
| VPS (Vultr, Hetzner) | €5-15/mo | Medium (manual setup) | Good if you configure it properly |
| Oracle Always Free | €0 | High | ARM CPU, low single-core, not recommended |
For 10 players who want zero maintenance, a managed game server host with dedicated Ryzen 9 hardware and NVMe storage will outperform self-hosting on most home setups. The bottleneck on home hosting is almost always upload speed and router NAT latency, not the PC itself.
Summary: the spec to buy for 10 players in 2026
If you're choosing a hosted plan or building a dedicated box for exactly 10 players on vanilla or Paper Minecraft:
- RAM: 8 GB
- CPU: AMD Ryzen 5000/7000 series or equivalent, 3.5 GHz+ boost
- Storage: NVMe SSD, 20+ GB free
- Network: 25 Mbps upload, sub-50ms to your players
- Java: Java 21
- OS: Ubuntu 22.04 LTS
That will run comfortably at 20 TPS with all 10 players active, even with moderate plugin load. For heavily modded servers, see our ATM10 server requirements guide or scale RAM to 12-16 GB.
