Running a Minecraft server is one thing - running a smooth Minecraft server is another. Here's everything you need to know to optimize your server for the best performance.
Server Startup Flags
The right JVM (Java Virtual Machine) flags can dramatically improve performance. Use the G1GC garbage collector with optimized heap sizes.
World Optimization
Pre-generate your world using Chunky or similar plugins. Set a world border and generate chunks before opening to players. This prevents lag when players explore new areas.
Plugin Optimization
Switch from Spigot to Paper for better performance. Use Spark to monitor performance and identify lag sources. Install ClearLag to remove excess entities automatically.
Server Configuration
Optimize your server properties: Set view distance to 8 and simulation distance to 6 for best balance. Adjust mob spawn rates in bukkit.yml.
Monitoring Performance
Use Spark Profiler and Timings reports to identify issues. Check server TPS regularly.
Hardware Recommendations
For optimal performance you need high single-thread CPU performance (3.5GHz+), minimum 4GB RAM (8GB+ recommended), M.2 NVMe SSD storage, and low-latency network connection.
