In this guide, you will learn how to fix common lag sources on your Minecraft server and configure settings to improve performance. While Minecraft has various performance pitfalls, even just changing a few default settings can significantly reduce lag.
Daily Restarts
The first thing you'll want to do is create an automatic daily restart schedule; this serves to keep your resource usage under control while ensuring your server has a fresh load once every 24 hours.
To create a schedule follow this guide.
Optimizing Server Properties
The most recommended way to reduce lag on any Minecraft server is to optimize your server.properties file.
- 1Access the Game Host Bros Panel and stop your Minecraft server.
- 2In the sidebar, go to
File Managerand openserver.properties. - 3Set
sync-chunk-writes=false(1.16+ only). - 4Update
simulation-distanceandview-distancebased on your player count using the table below. - 5Start your server.
Recommended Settings
| Player Count | Simulation Distance | View Distance |
|---|---|---|
| 1-5 Players | 8 | 10 - 14 |
| 6-10 Players | 6 | 8 - 10 |
| 10-20 Players | 5 | 5 - 7 |
| 20+ Players | 3 - 4 | 5 |
If you lower the server view distance, players can still see further by installing client-side mods such as Distant Horizons or Bobby. Modded servers should use a lower simulation distance such as 5.
As an additional recommendation, consider enabling Aikars Flags from the Startup Parameters page of the game panel. Aikars Flags were created to help optimize performance, and are especially effective for older versions of Minecraft.
Picking the Right Server Type
Running a completely Vanilla Minecraft server (the official jar from Mojang) is often performance-intensive. Unless you need 100% mechanical parity with Vanilla, switching your server software is the most effective solution to lag.
- Paper: The best choice for most server admins. It offers a wide range of plugins, high configurability, and excellent performance optimizations.
- Fabric: A good choice if you want very lightweight mods, but requires specific performance mods (like Lithium) to match Paper's optimization.
To change your server software, please refer to our guide on how to select the correct version for your server.
Do not change your version if you are running a pre-configured modpack.
