FerriteCore (Fabric) - Memory Usage Optimization

This page is for the Fabric version. For Forge users, a separate version of the modification is available.

This mod significantly reduces Minecraft's RAM consumption through several different optimization methods. A detailed technical description of all implemented changes can be found in the corresponding documentation.

Memory savings depend on the specific modpack. For example, in version 2.5.9 of the All Of Fabric 3 pack, RAM usage (heap size) decreases from 1792 MB to 984 MB. These metrics were recorded after generating a world with a fixed seed and waiting for two minutes. It's worth noting that the testing methodology differs from the Forge version, where measurements were taken at the title screen. This is due to the different behavior of Forge and Fabric when initializing caches that are optimized by this mod.

Frequently Asked Questions

Should I install the mod on the server or just the client?

Although some optimizations work only on the client side, there are highly effective improvements that are relevant for the server as well. Therefore, it's recommended to install the mod on both sides.

Is the mod compatible with other modifications?

In most cases - yes. The only exception is Hydrogen, which is compatible with all recent FerriteCore versions only on Minecraft versions where Hydrogen is officially supported. This means that builds for versions 1.18+ are incompatible with Hydrogen, as this project has been archived and no longer receives updates for these versions.
