| Medium (10-50 players) | 4 cores @ 3.5GHz+ | 8-12GB | NVMe SSD |
| Large (50+ players) | 8+ cores @ 4.0GHz+ | 16GB+ | NVMe SSD |
Solution 2: Java Virtual Machine Tuning
Garbage Collector Selection
Choose the right GC for your server size:
# Small servers (1-20 players)
-XX:+UseSerialGC
-XX:MaxGCPauseMillis=200
# Medium servers (20-100 players)
-XX:+UseG1GC
-XX:MaxGCPauseMillis=150
-XX:G1HeapRegionSize=16M
# Large servers (100+ players)
-XX:+UseZGC
-XX:ZCollectionInterval=30
Memory Optimization

-XX:+UseCompressedOops
-XX:+UseCompressedClassPointers
-XX:+UseStringDeduplication
-XX:+OptimizeStringConcat
-XX:+UseCompressedStrings
-XX:NewRatio=2
-XX:SurvivorRatio=8
Solution 3: Server Configuration
World Generation Settings
Optimize world generation for performance:
{
"world": {
"viewDistance": 8,
"simulationDistance": 6,
"chunkGeneration": {
"threads": 4,
"queueSize": 200,
"batchSize": 16
},
"entityProcessing": {
"maxEntitiesPerChunk": 50,
"activationRange": 64,
"updateInterval": 1
}
}
}
Network Configuration
Optimize network settings for better performance:
{
"network": {
"compression": true,
"compressionLevel": 6,
"tcpNoDelay": true,
"sendBufferSize": 65536,
"receiveBufferSize": 65536,
"maxConnections": 100,
"timeout": 30000
}
}
Solution 4: Plugin and Mod Optimization
Performance Monitoring
Track plugin performance impact:
- Use profiling tools to identify resource-heavy plugins
- Monitor plugin execution times
- Check for memory leaks in custom code
- Benchmark plugin performance with and without each mod
Plugin Optimization Best Practices
| Optimization Area | Best Practice | Performance Gain |
|---|---|---|
| Event Handling | Use efficient event listeners | 15-25% improvement |
| Database Queries | Implement connection pooling | 20-30% improvement |
| Caching | Cache frequently accessed data | 30-50% improvement |
| Async Operations | Use async for I/O operations | 40-60% improvement |
Solution 5: System-Level Optimization
Operating System Tuning
Optimize your OS for server hosting:
# Linux kernel parameters (/etc/sysctl.conf)
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
net.ipv4.tcp_rmem = 4096 87380 16777216
net.ipv4.tcp_wmem = 4096 65536 16777216
net.ipv4.tcp_congestion_control = bbr
vm.swappiness = 10
Process Priority Management
Set appropriate priorities for server processes:
# Set high priority for server process
nice -n -10 java [server_arguments]
# CPU affinity for dedicated cores
taskset -c 0-3 java [server_arguments]
# I/O priority for better disk performance
ionice -c 1 -n 7 java [server_arguments]
Performance Monitoring
Key Metrics to Track
CPU Usage
Monitor processor utilization and thread performance
Memory Usage
Track heap usage and garbage collection frequency
Network Latency
Measure ping times and packet loss
TPS (Ticks Per Second)
Server game loop performance indicator
Disk I/O
Monitor read/write speeds and queue depth
Monitoring Tools
Use these tools for comprehensive monitoring:
- Prometheus + Grafana: Advanced metrics visualization
- Java Mission Control: JVM performance analysis
- htop/nmon: System resource monitoring
- Wireshark: Network traffic analysis
- Custom Scripts: Automated performance alerts
Troubleshooting Performance Issues
Common Performance Problems
| Symptom | Cause | Solution |
|---|---|---|
| Low TPS (<15) | CPU bottleneck or inefficient plugins | Upgrade CPU or optimize plugins |
| Frequent GC pauses | Insufficient RAM or poor GC tuning | Increase heap size or tune GC |
| High latency | Network issues or server overload | Optimize network or reduce load |
| Chunk loading delays | Slow storage or insufficient I/O | Upgrade to SSD or optimize I/O |
Performance Testing
Regular performance testing methodology:
- Establish baseline performance metrics
- Simulate typical player load patterns
- Test with stress scenarios (maximum capacity)
- Monitor resource usage during testing
- Document results and compare over time
Pro Tip: Implement automated performance testing that runs during low-traffic periods. This helps identify performance regressions before they impact players.
Advanced Optimization Techniques
Load Balancing
For very large servers, consider these strategies:
- Distribute world processing across multiple instances
- Use proxy servers for connection handling
- Implement database clustering for data storage
- Separate chat and auxiliary services
Caching Strategies
Implement multi-level caching:
# Example caching configuration
{
"cache": {
"worldData": {
"type": "redis",
"ttl": 300,
"maxSize": "1GB"
},
"playerData": {
"type": "memory",
"ttl": 60,
"maxSize": "500MB"
},
"pluginData": {
"type": "file",
"ttl": 3600,
"maxSize": "2GB"
}
}
}
Maintenance and Updates
Regular Optimization Tasks
- Weekly performance review and metric analysis
- Monthly JVM tuning adjustments
- Quarterly hardware assessment and upgrades
- Continuous plugin optimization and updates
