Startup settings define how your server boots — which version to run, how much memory to allocate, and any custom parameters.
Accessing startup settings
Open your server panel and click the Startup tab. You’ll see:
- Startup command — the exact command executed on boot (read-only for most games)
- Variables — configurable values like server version, jar filename, and license key
- Docker image — the runtime environment (usually don’t change this)
Common variables
Minecraft
FiveM
Memory allocation
Memory is set at the plan level. To adjust:
- Determine your workload needs.
- From the client area, request an upgrade or downgrade.
For Minecraft, allocate 1–2 GB per 20 players plus overhead for plugins/mods. Modded servers often need 4–8 GB minimum.
Custom JVM flags (Minecraft)
Optimized flags like Aikar’s flags reduce garbage collection pauses:
Most CrazyNode Minecraft eggs apply optimized flags automatically. Advanced users can override them via a custom startup variable.
Incorrect JVM flags can prevent the server from starting. Test after any change.
