Optimizing Your Minecraft Server Performance with Rack-Point

When setting up your Minecraft server with Rack-Point, you select the resources that best fit your gameplay style and server needs. Different server types and mods require varying amounts of CPU, RAM, and storage to run smoothly — we’re here to help you find the right balance and optimize your server’s performance.

Tailor Your Server Resources to Your Gameplay

Whether you're running a simple Vanilla server or a heavily modded Forge environment, resource allocation plays a crucial role in how well your server performs. Consider these key factors:

• CPU Power: More players and complex mods demand higher processing power. Vanilla servers for small groups can operate well on moderate CPU allocations, while modded servers and larger communities benefit from increased CPU availability.
• Memory (RAM): RAM impacts player capacity and server responsiveness. Lightweight servers like Vanilla or Paper can run smoothly with moderate RAM, but Forge and other heavy modpacks generally need more memory to avoid lag.
• Storage: Larger worlds, mods, and backups require ample disk space to maintain smooth operation, so plan storage according to your server’s scope.

Choosing the Right Server Software

Your choice of server software can significantly affect performance and resource requirements:

• Vanilla: The classic Minecraft experience with minimal overhead, ideal for small servers or simple gameplay.
• Paper: An optimized fork of Spigot, improving performance and allowing plugins without the heavy resource use of mods — a popular choice for performance-focused servers.
• Forge: Designed for running multiple mods, Forge requires more CPU and RAM but unlocks extensive gameplay customization.

Matching your server software with the right resources is key to keeping gameplay smooth and enjoyable.

Advanced Optimization: Java Arguments

Optimizing your Java runtime parameters can enhance performance by improving memory management and garbage collection. Here are some recommended Java arguments to boost your Minecraft server's efficiency:

-XX:+UseG1GC -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=200 -XX:+UnlockExperimentalVMOptions 
-XX:+DisableExplicitGC -XX:G1NewSizePercent=40 -XX:G1MaxNewSizePercent=50 -XX:G1HeapRegionSize=16M 
-XX:G1ReservePercent=15 -XX:G1HeapWastePercent=5 -XX:G1MixedGCCountTarget=4 -XX:InitiatingHeapOccupancyPercent=20 
-XX:G1MixedGCLiveThresholdPercent=90 -XX:G1RSetUpdatingPauseTimePercent=5 -XX:SurvivorRatio=32 -XX:+AlwaysPreTouch 
-Dusing.aikars.flags=https://mcflags.emc.gs -Daikars.new.flags=true

These flags help reduce lag spikes caused by garbage collection and optimize how memory is allocated and recycled.

Server Properties: Start with Defaults, Adjust as Needed

Many server.properties settings have sensible defaults that work well for most situations. We recommend starting with the default values and only adjusting if you encounter performance issues or want to tailor gameplay experience. Key properties to keep an eye on include:

• view-distance: Controls how many chunks are loaded around each player. Lowering this reduces CPU and memory usage but also limits visible world range. Start with the default (usually 10) and reduce if performance drops.
• simulation-distance: Determines how far away entities and blocks are actively processed. Keep the default for balanced performance; reduce if experiencing lag with many entities.
• max-entity-collisions: Limits how many collision checks occur per entity. Defaults are typically sufficient, but lowering can help on very crowded servers.
• tick-distance: Sets how far away entities are updated each tick. Adjust only if necessary after monitoring server load.
• allow-nether: Disabling unused dimensions like the Nether can save resources if not needed.

By monitoring your server’s performance and player experience, you can fine-tune these settings gradually to find the ideal balance.

Performance-Boosting Plugins and Tools

Using the right plugins can also make a big difference. Some popular performance-focused plugins include:

• Paper or Purpur: High-performance forks that optimize server speed and stability.
• ClearLag: Automatically removes unnecessary entities to reduce lag.
• Villager Optimiser: Enhances villager AI performance, reducing server strain.
• EntityTrackerFixer: Optimizes entity tracking to minimize lag.
• Chunky: Pre-generates chunks to prevent lag spikes during exploration.

Monitor and Adjust Regularly

Performance tuning is an ongoing process. Use these tools to keep an eye on your server’s health:

• Spark: Detailed performance insights and lag source detection.
• Timings (Paper/Purpur): Built-in analysis of server tick times and bottlenecks.
• VisualVM: Advanced Java profiling for deep performance analysis.

By regularly monitoring and adjusting your server’s resources and settings, you’ll ensure a smooth and enjoyable experience for all your players.

Flexible Resources to Match Your Needs

With Rack-Point, you can easily customize and scale your server’s CPU, RAM, and storage as your community grows or your gameplay changes. Whether you want to host a cozy Vanilla world or a feature-rich modded server, you control the power needed to keep things running smoothly.
