This mod is absolutely incredible. The performance gains that can be made using this mod on both the server and client are unmistakable, especially in combination with many larger mods.
I would go as far as claiming Ferrite Core as the most important optimisation mod, as RAM is often something minecraft is very tight on, alongside CPU. As a byproduct of reducing RAM, ferrite core often actually frees up CPU by preventing there being such a load on GC.
If you play Minecraft, use this mod. I've never encountered it causing any issues outside of other broken mods breaking it
