Optimizing Server Performance (Build 41)
Advanced techniques to maximize your Project Zomboid server performance for Build 41
Understanding PZ Server Performance (Build 41)
Project Zomboid Build 41 servers can be resource-intensive, especially with many players, mods, and zombies. This guide covers optimization techniques specific to Build 41 servers to ensure smooth gameplay even under heavy load.
Build 41 Performance Factors
- Number of active players
- Zombie population and active cells
- Installed mods (quantity and quality)
- Map size and custom maps
- Server hardware allocation
Build 41 Server Configuration Optimization
Zombie Population Settings
Zombie count has the largest impact on server performance. Finding the right balance is crucial.
Recommended settings for Build 41:
PopulationMultiplier = 0.5 to 1.0PopulationStartMultiplier = 0.5PopulationPeakMultiplier = 1.5RespawnHours = 72For servers with 20+ players, consider reducing these values further.
Memory Allocation
Proper Java memory allocation is essential for preventing crashes and lag spikes in Build 41.
Recommended JVM arguments for Build 41:
-Xms4G -Xmx4G-XX:+UseG1GC -XX:G1HeapRegionSize=8M-XX:+ParallelRefProcEnabled -XX:+DisableExplicitGCAdjust -Xms and -Xmx values based on your server plan (e.g., 6G for 8GB plans).
Map and Cell Settings
Limiting active cells and map size can significantly improve performance.
Recommended settings for Build 41:
Map.AllowWorldSimulation = trueSaveWorldEveryMinutes = 30PlayerSafehouse.AllowNonResidential = falseSleepAllowed = trueConsider using smaller map areas for servers with 30+ players.
Network Optimization
Fine-tuning network settings can reduce lag and improve player experience.
Recommended settings for Build 41:
PingFrequency = 15PingLimit = 400WorkshopItems = (keep this list minimal)MaxPlayers = (based on your plan)Build 41 Specific Optimizations
These settings are specifically tuned for Build 41 servers:
Map.ActiveCellLimit = 256 (default for Build 41).EnableSnowOnGround = false for better performance.VehicleSimulationDistance = 100 (Build 41 default).ZombieConfig.PathFindMaxNodes = 2000 (Build 41 default).Server Maintenance for Build 41
Regular Restarts
Schedule automatic restarts every 12 hours to clear memory leaks (more frequent than Build 42).
World Item Cleanup
Use admin commands to periodically clean up excess items and vehicles in the world.
Log Rotation
Delete old log files regularly to prevent disk space issues.
Mod Management
Regularly update mods and remove unused ones to prevent conflicts and performance issues.
Build 41 vs Build 42 Performance
Key differences between Build 41 and Build 42 performance characteristics:
| Feature | Build 41 | Build 42 |
|---|---|---|
| Rendering Engine | Legacy | New PZ Framework |
| Zombie AI | Basic | Enhanced |
| Memory Usage | Lower | Higher |
| Network Protocol | Basic | Improved |
| World Simulation | Limited | Expanded |
