If your Minecraft server is lagging, it can ruin the gameplay experience. This guide will help you fix lag on Aternos and other servers by optimizing settings, reducing unnecessary resource usage, and preventing lag machines.

Common Causes of Minecraft Server Lag

• Server Lag (TPS Drop) – Caused by too many entities, unoptimized plugins, or bad hosting.
• Client Lag (FPS Drop) – Caused by high graphics settings, shaders, or too many mods.
• Network Lag (High Ping) – Caused by slow internet or distant server locations.

Best Aternos & Minecraft Server Settings to Reduce Lag

For Aternos users, apply these settings:

• View Distance: Set to 6.
• Simulation Distance: Set to 4.
• Max Tick Time: Set to 60000.
• Use Paper or Purpur for better performance.

For other hosts, tweak these files:

• spigot.yml – Reduce entity-activation-range to lower CPU usage.
• bukkit.yml – Increase ticks-per-animal-spawns to 400.
• server.properties – Lower view-distance for improved performance.

Remove Laggy Plugins & Mods

Some plugins cause more lag than they fix. Avoid these:

• ClearLag – Can remove important items and entities.
• Heavy anti-cheat plugins – Overload the server with checks.
• Too many automated plugins – Increase processing load.

Instead, use performance-friendly plugins like:

• FarmLimiter – Limits mobs per chunk.
• Paper or Purpur – Optimized for high-performance servers.
• LagAssist – Automatically reduces lag.

Prevent Lag Machines & Redstone Overload

Some players create lag machines using redstone or mobs. Stop them by:

• Installing CoreProtect or WorldGuard to monitor redstone usage.
• Disabling minecart stacking to prevent excessive entities.
• Using AntiRedstoneClock to block redstone spam.

Upgrade Hosting for More Power

If your server still lags, consider upgrading:

• Increase RAM (2GB+ for small servers, 4GB+ for large servers).
• Switch to a better host like Shockbyte, PebbleHost, or ScalaCube.
• Choose a server location closer to players to reduce ping.

Reduce Mob, Hopper, and Entity Lag

Entities like mobs, hoppers, and redstone circuits can cause major lag. Fix them by:

• Using FarmLimiter to limit mobs per chunk.
• Reducing hopper checks in spigot.yml.
• Preventing unlimited redstone clocks with anti-lag settings.

Pre-Generate the World to Reduce Lag

Pre-generating chunks reduces lag from world generation:

• Use WorldBorder and run /wb fill.
• Use Chunky to pre-load chunks before players explore.
