How Much RAM A Java Server Needs
Vanilla and lightly plugged Paper servers are comfortable on 2 to 6 GB for a handful of friends. Plugin servers with a world border, an economy and a few dozen players sit naturally at 8 GB, which is why it is our most popular tier. Large modpacks are the expensive case: Forge and Fabric packs with hundreds of mods routinely want 12 to 16 GB before they stop stuttering on chunk generation.
Because pricing is a flat $2.50 per GB of RAM, sizing up is a prorated billing change rather than a migration. Cores follow memory on our tiers: three up to 6 GB, four at 8 GB, and five from 12 GB upward, which matters for pregeneration and for the async work Paper offloads from the main thread.
