Optimizing Memory Usage for Large VEIN Worlds
Keep the server running smoothly even as player bases scale up. Memory leaks and massive base builds can bring a server to a grinding halt if unoptimized.
The Root of Memory Spikes
Dedicated servers in Unreal Engine titles cache massive amounts of data: actor locations, dropped items on the floor, dormant zombies, and player structures. Over time, RAM usage naturally climbs.
Best Practices for Server Admins
1. Scheduled Restarts
The single most effective optimization is a daily server restart. This flushes the cached memory and forcefully drops RAM usage back to baseline. Configure your control panel to issue a graceful shutdown command at 4:00 AM daily.
2. Cleanup Variables
Modify Engine.ini to aggressively delete discarded items:
[/Script/Vein.GarbageCollection]
DroppedItemLifespanTemplate=3600
DestroyDeadBodiesAfter=300This ensures that a can of soda thrown on the ground vanishes after 1 hour (3600 seconds), and dead zombie corpses despawn after 5 minutes (300 seconds), freeing up object count limits heavily.
3. Player Count Limits
Do not set your MaxPlayers to 64 if you only possess 8 GB of RAM. A comfortable rule of thumb is allocating ~400 MB of RAM per active player roaming the map generating chunks. A 16 GB RAM server comfortably hosts 20-30 players.
