High CPU/RAM Usage

High CPU or RAM usage can cause lag, rubber-banding, and server crashes. This guide helps you diagnose and resolve performance issues.

Open the Overview tab in your server panel. The real-time graphs show CPU and RAM usage over time.

• CPU consistently above 80% — your server is CPU-bound. Consider upgrading or reducing load.
• RAM above 90% — risk of OOM crash. Upgrade or reduce memory usage.

• Too many plugins/mods — each one uses CPU and RAM. Audit your list and remove unused ones.
• World size too large — Rust and Minecraft worlds grow over time. Pre-generate and set borders.
• Entity overflow — too many entities (mobs, items, dropped objects) bog down the server.
• Memory leaks — some plugins gradually consume more RAM over time. Scheduled restarts help.
• Player count exceeds plan capacity — more players = more resources needed.

1. Upgrade your plan — the simplest fix for a growing community.
2. Schedule automatic restarts — restart every 6–12 hours to clear memory leaks. Set this in the Schedule tab.
3. Reduce render/view distance — fewer chunks loaded = less CPU and RAM.
4. Limit entities — use game-specific settings to cap mob spawns, dropped items, etc.
5. Profile with tools — use spark (Minecraft), oxide.plugins timing (Rust), or the server's built-in profiler.
6. Optimize configs — see our game-specific setup guides for performance tuning tips.
