Palworld Server Performance Optimization

How to optimize your Palworld server for better FPS, less lag, and lower memory usage.

Palworld servers have known memory leak issues. Here's how to keep things running smoothly.

Key Settings to Tune

In Pal/Saved/Config/LinuxServer/PalWorldSettings.ini:

Setting	Default	Recommended	Impact
`BaseCampWorkerMaxNum`	`15`	`10–15`	Biggest lever — each worker runs AI
`DropItemMaxNum`	`3000`	`2000`	Fewer dropped items in world
`DropItemAliveMaxHours`	`1.0`	`0.5`	Faster cleanup of dropped items
`PalSpawnNumRate`	`1.0`	`0.8–1.0`	Fewer Pals = less CPU
`MaxBuildingLimitNum`	`0`	`5000–10000`	Prevents structure bloat (0 = unlimited)
`ServerReplicatePawnCullDistance`	`15000`	`8000–10000`	Pal sync range — lower = less network
`bEnableInvaderEnemy`	`True`	`False` if RAM issues	Raids contribute significantly to memory leaks

RAM Requirements

Players	Minimum	Recommended
1–8	8 GB	12 GB
8–16	12 GB	16 GB
16–32	16 GB	32 GB

Schedule Regular Restarts

The server has a known memory leak. Schedule restarts every 4–6 hours to clear accumulated memory.

In the XGamingServer Panel, click Schedules in the sidebar to set up automatic restarts.

Performance Monitoring

Use the REST API to check server health:

curl -u admin:password http://localhost:8212/v1/api/metrics

Target values:

Server FPS: 60+ (good), below 50 is poor
RAM under 8 GB is healthy, over 12 GB is concerning

Engine.ini Optimizations

Create or edit Engine.ini in the same config folder as PalWorldSettings.ini:

[/Script/OnlineSubsystemUtils.IpNetDriver]
NetServerMaxTickRate=120

[/Script/Engine.GarbageCollectionSettings]
gc.TimeBetweenPurgingPendingKillObjects=60

General Tips

Disable raids (bEnableInvaderEnemy=False) if experiencing RAM issues — this is a major contributor
Use SSD storage for save files
Linux servers run more efficiently than Windows on long uptimes
Reduce BaseCampWorkerMaxNum before reducing PalSpawnNumRate — worker AI is more expensive than wild Pal spawns
