Performance Optimization

Performance is a critical aspect of any FiveM server. This section provides comprehensive guides for optimizing both server and client performance to ensure a smooth experience for all players.

Understanding FiveM Performance

FiveM performance depends on several key factors:

1. Server Hardware: CPU, RAM, and network capabilities
2. Resource Efficiency: Well-optimized scripts and resources
3. Database Performance: Query optimization and connection management
4. Network Configuration: Proper network settings and optimizations
5. Client-side Performance: Client FPS and resource usage

Available Guides

Performance Monitoring Tools

CitizenFX provides several built-in tools for monitoring and optimizing performance:

1. Resource Monitor (resmon): Shows real-time resource usage and performance metrics
2. Profiler: Records detailed performance data for analysis
3. Network Monitor: Displays network usage and latency information
4. Debug Tools: Provides detailed debugging information

For more information on these tools, visit the Common Tools section.

Best Practices

General Performance Tips

1. Start with a Clean Base: Begin with a minimal server setup and add resources incrementally
2. Regular Monitoring: Use monitoring tools to identify bottlenecks
3. Scheduled Maintenance: Implement regular server restarts and maintenance
4. Resource Management: Keep only necessary resources running
5. Stay Updated: Keep your server artifacts and resources up to date

Common Performance Issues

Server-side Issues

1. High CPU Usage: Often caused by inefficient scripts or too many entities
2. Memory Leaks: Resources not properly cleaning up entities or data
3. Database Bottlenecks: Slow or unoptimized database queries
4. Network Congestion: Too much data being synchronized

Client-side Issues

1. Low FPS: Often caused by too many entities or graphic-intensive resources
2. Stuttering: Usually related to synchronization issues or resource loading
3. Long Loading Times: Can be caused by large resource files or inefficient loading
4. Connection Issues: Network configuration problems or server overload

Performance Benchmarking

Establishing performance benchmarks helps track improvements over time:

1. Server Metrics:

   • CPU usage percentage
   • Memory consumption
   • Network bandwidth usage
   • Entity count (vehicles, peds, objects)

2. Client Metrics:

   • Frames per second (FPS)
   • Loading times
   • Resource memory usage
   • Network latency

Advanced Performance Techniques

For advanced users, consider these techniques:

1. Custom Resource Scheduling: Prioritize critical resources
2. Entity Management Systems: Implement custom entity culling
3. Asynchronous Processing: Use async patterns for intensive operations
4. Distributed Systems: Split functionality across multiple servers
5. Resource Dependency Optimization: Minimize dependencies between resources

For specific optimization techniques, refer to the individual guides in this section.

Server Performance

Monitor Resource Usage

Regularly check resource usage statistics to identify potential issues. High CPU or memory usage by specific resources can indicate inefficiencies that need addressing. Use the built-in Resource Monitor (resmon) for real-time monitoring.
