🛠️ How to Optimize a Modded Minecraft Server (Forge, Mohist, Arclight, CatServer, Magma)

This guide will show you how to troubleshoot and reduce lag on your modded Minecraft server, including various methods to identify and mitigate lag.

Important: This guide is specifically designed for modded Minecraft Forge servers.

🔧 Common Solutions:

One of the simplest ways to reduce lag is by decreasing the server's view distance.

Entity-caused lag is one of the most common types of lag. This can happen when there is a large number of entities on your server.

🛠️ Server Type Limitations:

Server plugins in Minecraft are powerful tools that enhance gameplay and offer various features. However, they may not optimize game performance to the same level as mods. This is because plugins operate within the limitations and restrictions of the Spigot server framework.

On the other hand, mods have fewer restrictions and can directly modify the game’s code and mechanics. As a result, modded servers offer more extensive opportunities for optimizations and performance improvements.

⚙️ Optimization Mods:

📋 FastWorkbench: Download here

FastWorkbench is a Minecraft Forge mod that improves crafting performance by caching recipes and reducing unnecessary recipe checks. It addresses a bug introduced in Minecraft 1.12 that caused temporary freezes when shift-click crafting.

📋 FastFurnace: Download here

Created by the same author as FastWorkbench, FastFurnace is a mod for Forge that improves the TPS (Ticks Per Second) performance of furnaces, blast furnaces, and smokers. Similar to FastWorkbench, this is achieved by caching the last-used recipe and avoiding unnecessary registry lookups, speeding up the processing time of furnace blocks.

📋 AI Improvements: Download here

AI Improvements is a Forge mod focused on optimizing AI performance by making low-level modifications to AI behavior. It addresses common issues such as entity overload, performance impact from large zombie swarms, and inefficient task handling. Moreover, AI Improvements does not need to be installed on the game client alongside the server.

By improving how AI functions, the mod enhances server performance without the need to cut down on extensive mods. It offers various configurable features, such as disabling specific AI segments and replacing EntityLookHelper with a more efficient version, leading to significant reductions in CPU usage, especially in older Minecraft versions.
