Do these mods need to be installed on the client side?

Most of the recommended optimization mods like Lithium and Krypton are server-side only and do not need to be installed by players.

Can I edit my server's startup flags to improve performance?

To add your own JVM flags, set a custom startup command in your server's **Startup** tab. You can set your own startup command, JVM flags included, in the **Startup** tab; the memory setting follows your plan.

How do I upgrade my RAM on AwakeNode?

You can upgrade your plan (choose **Upgrade** on your server's page). Once upgraded, your server's RAM allocation updates automatically without any manual config changes.

What should I do if a mod causes my server to crash?

Use the File Manager to remove the mod from the mods folder. If the issue persists, check your logs or contact support.

Best Fabric Optimization Mods for Minecraft 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

Navigate to your server's control panel.
Open the Files tab and upload these mods to the mods folder, then restart.

On other hosts / manually

Download the correct .jar files for your specific Minecraft version from Modrinth or CurseForge.
Connect to your server via SFTP.
Upload the files into the mods folder located in your server's root directory.
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: To add your own JVM flags, set a custom startup command in your server's Startup tab. You can set your own startup command, JVM flags included, in the Startup tab; the memory setting follows your plan.
Version Compatibility: Always ensure your mods match your server's version exactly. You can use the Startup tab to switch versions if you need to align your environment with specific mod releases.
