Server Lag & Performance Issues

Updated 2026-03-18

Server Lag & Performance

Types of Lag

1. Network lag (high ping) — Players far from server location
2. Server lag (low TPS) — Server can't process fast enough
3. Client lag (low FPS) — Player's computer is too slow (not a server issue)

Fix Network Lag

• Choose a server location closest to the majority of players
• Check your internet connection and use wired instead of WiFi
• Close bandwidth-heavy applications
• Use a gaming VPN if routing is poor

Fix Server Lag

1. Upgrade RAM — Most common fix for lag
2. Reduce view/render distance in server config
3. Limit entity counts — Too many animals, items, or dropped items
4. Use performance-focused server software:

• Minecraft: Paper/Purpur (instead of Vanilla or Forge)
• Rust: CarbonMod (faster than Oxide)
• Valheim: ValheimPlus (performance tweaks)

1. Schedule regular restarts — Clears memory leaks
2. Clean up the world — Remove unused chunks, decay abandoned bases

Performance Monitoring

• TPS (Ticks Per Second): Target is 20 for Minecraft, 30 for most others
• RAM usage: Should stay below 85% of allocated
• CPU usage: Spikes are normal, sustained 100% is problematic
• Check in Dashboard → Server → Performance
