Troubleshoot Server Performance Issues

Identifying Performance Problems

Monitor server performance through console output and player feedback. Lag typically stems from too many entities, excessive chunk loading, or resource-intensive plugins. Use console commands to check active player counts and entity numbers.

Enable debug logging in configuration files to identify which systems consume the most resources. Check that your hardware meets minimum requirements for your player count.

Optimization Steps

Reduce view distance if players experience lag — this limits chunk rendering. Disable unnecessary plugins or replace heavy ones with lighter alternatives. Increase allocated RAM if the server frequently runs out of memory.

Regularly restart the server to clear accumulated memory leaks. Optimize world files by removing unused chunks. Monitor network bandwidth to ensure your connection can handle player traffic. Test changes incrementally to identify what improves performance.
