Frequently asked questions

How do I start using ServerCore after installing it?
Run `/servercore settings` to open the configuration menu and review the default optimizations. Use `/servercore status` to see what dynamic adjustments are currently active on your server. Most features work automatically, but you can customize thresholds and behaviors through the settings command.
What does Entity Activation Range do?
Entity Activation Range reduces the distance at which mobs and entities process their AI and behavior when players aren't nearby. This prevents distant mobs from consuming server resources, significantly cutting lag from large mob farms or spawning areas.
How do I fix lag from my villager trading hall?
ServerCore's villager lobotomization feature disables unnecessary AI for villagers that aren't actively trading, reducing their performance impact. You can also adjust breeding caps through `/servercore settings` to prevent excessive villager breeding in confined spaces.
Can I see which entities or blocks are causing lag?
Use `/statistics entities` to see which entity types are consuming the most resources, or `/statistics block-entities` to identify problematic block entities. This helps you pinpoint what's creating lag spikes on your server.
