About Minecraft Server Requirements
Running a Minecraft server requires careful consideration of hardware resources. The requirements vary significantly based on player count, server type, plugins, and world size. This calculator provides estimates to help you choose the right hosting plan or hardware configuration.
Paper vs Spigot Performance
Paper is a fork of Spigot that offers significant performance improvements. It includes optimizations for chunk loading, entity handling, and redstone mechanics. For most servers, especially those with many players or plugins, Paper is the recommended choice as it can reduce RAM usage by up to 20% and CPU load by up to 30% compared to Spigot.
Impact of Plugins on Server Performance
Each plugin adds overhead to your server. Some plugins like WorldEdit, Dynmap, and large economy plugins can significantly increase resource usage. As a general rule, each plugin adds approximately 50-100MB of RAM usage, but this varies widely based on the plugin's complexity and configuration.
World Size Considerations for Minecraft Servers
Larger worlds with more explored chunks require more RAM to keep loaded. Additionally, complex redstone contraptions, large numbers of entities (like animals, monsters, or item frames), and automated farms can all increase the resource requirements of your server.
Optimizing Minecraft Server Performance
Beyond choosing the right hardware, you can optimize your Minecraft server by:
- Setting an appropriate view distance (8-10 is recommended)
- Limiting entity spawns and item despawn times
- Using pre-generated worlds to reduce chunk generation load
- Regularly pruning unused chunks to keep world sizes manageable
- Using performance-focused plugins like Clearlag or Paper's built-in optimizations
Frequently Asked Questions
How accurate is this calculator?
This calculator provides estimates based on typical Minecraft server requirements. Actual resource usage may vary depending on specific plugins, world generation settings, player activity, and other factors. We recommend starting with our estimates and monitoring performance to adjust as needed.
Why is Paper recommended over Spigot?
Paper is a fork of Spigot that includes numerous performance optimizations. It typically offers better TPS (ticks per second) rates, reduced lag, and lower resource usage compared to Spigot. For most servers, especially those with many players or plugins, Paper provides a more stable and efficient experience.
How much does each plugin impact performance?
Plugin impact varies significantly. Simple plugins might add minimal overhead, while complex ones like Dynmap or WorldGuard can increase RAM usage by 100-500MB or more. Our calculator accounts for average plugin resource usage, but specific plugins may require more or less resources than estimated.
Can I run a server on my home computer?
Yes, for small servers with few players, a home computer can work. However, you'll need a stable internet connection with good upload speed, and your computer will need to stay on whenever the server is running. For better performance and reliability, dedicated hosting is recommended for servers with more than 5-10 players.
How much bandwidth does a Minecraft server use?
A Minecraft server typically uses about 50-100MB per hour per player. For a 10-player server running 24/7, this translates to approximately 360-720GB per month. Ensure your hosting plan or home internet connection can handle this traffic volume.
Do modded servers require more resources?
Yes, modded servers (like Forge or Fabric) typically require significantly more RAM and CPU power than vanilla or Spigot/Paper servers. For modded servers, we recommend adding at least 1-2GB of RAM to our calculator's estimate, and ensuring you have a more powerful CPU.
