Quick answer: Vanilla with friends → 2-4GB. Paper with plugins for a community → 4-8GB. Modpacks → 8GB minimum, 12-16GB for the big ones. More RAM past your working set does nothing — single-thread CPU and disk speed matter more at that point.
The baseline numbers
Minecraft’s server is effectively single-threaded for world ticking — the RAM you buy holds the loaded chunks, entities and plugin state, not the tick speed. Size RAM to what the world holds, not to how fast you want it.
- Vanilla, 1-5 players: 2GB is genuinely enough for a friends server — ₹187/mo on our tiers.
- Paper + 10-30 plugins, 5-20 players: 4-6GB. Plugins are the variable — each one holds state per player and per chunk.
- Community server, 20-50 concurrent: 8GB. Past ~50 players it’s usually CPU-tick-bound, not RAM-bound.
- Forge/Fabric modpacks: 8GB floor. ATM-style packs (300+ mods) want 12-16GB — that’s the mod loading and registry, not players.
Where people overspend
Buying 16GB for a 6-friend vanilla world is the classic mistake — Java will grow the heap to fill it, use the extra as a cache, and you’ll feel zero difference versus 4GB. If your server hits the RAM ceiling it stutters; if it doesn’t, extra RAM is idle money.
The check: run the server a week, watch actual heap usage in the panel, then size to peak + headroom. Upgrading is a reboot, not a rebuild.
Where people underspend
Modpacks are the opposite trap — a 2GB plan technically "runs" a 200-mod pack the way a scooter technically pulls a trailer. Mod loading alone can eat 4-6GB before a player connects. The giveaway is GC pauses: the server freezes for seconds while Java garbage-collects a heap that’s too small.
If players report periodic lag spikes with fine TPS in between, the heap is thrashing — that’s a RAM problem, and it’s the one time buying up genuinely fixes it.
What actually limits performance
After RAM, the binding constraints are single-thread CPU speed (world tick), disk latency (chunk load/save), and — the one marketing pages hide — whether your node is oversold. A "16GB" plan on a contended node performs worse than honest 6GB on a quiet one.
Our nodes run dedicated allocation with swap disabled — and you can verify it: timings reports show GC pauses and tick times, and /tps at your peak hour tells you the truth better than any spec table.

FAQ
Is 4GB enough for 10 players?
On Paper with a sane plugin set, yes — comfortably. Vanilla even more so. The plugins matter more than the player count.
Does more RAM make Minecraft faster?
Only until the working set fits. Past that, extra RAM does nothing — the world tick is single-CPU-bound and won’t use it.
How much RAM for Forge/ATM modpacks?
8GB minimum for mid packs, 12-16GB for ATM-class 300+ mod packs. The mod count, not the player count, sets this.
How do I know if I’m RAM-limited?
Periodic freeze-then-recover cycles with otherwise-fine TPS = garbage collection thrashing = too-small heap. Timings reports show it directly.
Should I buy the size up just in case?
No — run a week at the honest size, check real heap usage, upgrade if it’s actually full. Upgrading is a reboot; pre-buying unused RAM is just spent money.
