Start conservative
Begin with a known map, a realistic MaxPlayers value, an owner Steam64 ID and the default Normal difficulty. Change one group of settings at a time so problems are attributable.
Use the current config format
Modern Unturned uses Config.txt and can create a difficulty-specific file. Empty values keep defaults and explicit values override level configuration. Use -LogGameplayConfig when diagnosing overrides.
Performance priorities
Keep the map and mod list deliberate, remove unused Workshop items, schedule restarts during quiet hours and watch save duration, memory use and tick responsiveness. More slots are not free performance.
Operational baseline
Use scheduled backups before updates, unique credentials, least-privilege admin access and an allowlisted plugin catalogue. Test updates on a copy before applying them to the live world.
