Best optimization mods Fabric 2026

Essential Fabric Optimization Mods

Optimising a Fabric server is the most effective way to ensure high TPS (Ticks Per Second) and a smooth experience for your players. By replacing inefficient vanilla processes with highly-optimised alternatives, you can significantly reduce server load.

Recommended Mods

• Lithium: A general-purpose optimisation mod that works by rewriting inefficient vanilla game logic. It is server-side only and provides a noticeable boost to tick times.
• FerriteCore: Reduces the memory footprint of the game by optimising how memory is allocated for various data structures.
• Krypton: Optimises the network stack, improving packet handling and reducing latency for players connecting to your server.
• Starlight: Rewrites the light engine to be significantly faster and more efficient than the default implementation.

Installing Mods on Your Server

On AwakeNode

1. Navigate to your server's control panel.
2. Use the Mod Installer to search for and install these mods with a single click. The panel handles the file placement and directory structure automatically.

On other hosts / manually

1. Download the correct .jar files for your specific Minecraft version from Modrinth or CurseForge.
2. Connect to your server via SFTP.
3. Upload the files into the mods folder located in your server's root directory.
4. Restart your server to apply the changes.

Server Performance Troubleshooting

If your server continues to experience lag after installing these mods, consider the following:

• Check your RAM: Ensure your plan provides enough memory for your mod count and player base. On AwakeNode, upgrading your plan automatically updates your -Xmx startup flags without manual configuration.
• JVM Flags: If you require specific Java garbage collection tuning or advanced startup flags, please open a Support ticket. Our team can apply these configurations to your instance safely.
• Version Compatibility: Always ensure your mods match your server's version exactly. You can use the Version Changer in the AwakeNode panel to switch versions if you need to align your environment with specific mod releases.
