Memory Usage Optimizations in Minecraft
This mod offers several effective methods to reduce Minecraft’s memory consumption. Various technical strategies are employed to optimize how data is stored and processed, resulting in improved performance and lower RAM requirements during gameplay.
Performance Comparison
The actual memory savings achieved by this mod depend on the modpack configuration. For example, in version 2.5.9 of All Of Fabric 3, using this optimization decreases RAM usage (heap size) from 1,792 MB to 984 MB.
To illustrate further, switching to Hydrogen for the same setup results in a heap size of 1,335 MB. These measurements were taken two minutes after world generation with a fixed seed, providing reliable benchmarks for memory efficiency.
Installation Recommendations
Although certain memory optimizations are tailored for the client side, there are significant enhancements that also benefit servers. For best results, install the mod on both client and server to maximize overall performance and efficiency.
Compatibility Information
This optimization mod works well alongside most other Minecraft mods. The primary exception is Hydrogen. FerriteCore and Hydrogen are compatible only on Minecraft versions where Hydrogen has active, official releases. Notably, Hydrogen is not compatible on Minecraft 1.18 or later, as there are no official Hydrogen builds for these versions.
