At a glance Estimate memory based on engine, modpack, players, and the world — not the slot limit.
Start with the gameplay type
Simple Vanilla for a small group usually needs less memory than a public server with multiple plugins. Modpacks and large packages may require a larger pool, as recommended by their creators.
Indicative Start Values
This is an approximate range, not a promise of smooth work. Number of players, release of the game, plugins and size of the map change the demand. For modpack first check his own recommendations.
- 1–2 GB — a small server for several friends;
- approximately 4 GB — Vanilla or basic survival with several plugins;
- 6-8 GB — larger plugin server or lightweight modpack;
- 10–16 GB — a larger community or requiring modpack;
- 24 GB+ — a large project, after confirming the needs in the measurements.
What increases wear?
- number and complexity of mods or plugins;
- exploration of new ware and large world size;
- multiple mobs, mechanisms and loaded areas;
- version of the game, simulation settings and player activity.
Don't assign all memory without need
The server and the operating system also need resources. Leave a margin for processes, cache drive and tools. Overallocation of memory does not guarantee liquidity, and the problem may result from CPU or plugin.
Measure and then change
When you run, watch the consumption in the panel, logs and fluidity during peak hours. Increase the package if you regularly lack memory when you exclude errors. Test the change with a similar number of players and similar world activity.
Back up first. Change one thing at a time.
Back up your working files, make a change and check the logs. Changing one thing at a time makes it easier to find the cause of a problem and restore your previous settings.
