What Affects Minecraft RAM Usage?

Player Count

More players generally mean more chunks, entities and activities being processed simultaneously.

Mods & Plugins

Large modpacks and complex plugins can significantly increase memory requirements.

World Size

Large and frequently explored worlds can increase memory usage because more chunks need to be loaded.

Redstone

Large redstone systems, farms and automated builds can increase server workload.

Mob Farms

High numbers of entities can increase both CPU and memory requirements.

Server Software

Vanilla, Paper, Forge, Fabric and NeoForge can have different resource requirements.
