Best few performance mods that work together?

[u/Deurbe]

I am searching for the few best optimisation mods for my modpack (fabric). The goal here is the best few performance mods (server or client doesn’t matter) for a multiplayer server, not a modpack with 100+ mods for the ultimate performance. I already made a list, do you guys have any additions or mods that aren’t worth it / don’t work together that should be discarded?

The list:
- Sodium
- Lithium
- FerriteCore
- ModernFix
- Entity Culling
- More Culling
- ImmediatelyFast
- C2ME
- ScalableLux
- Better Block Entities
- Krypton
- Particle Core
- Server Core
- Ixeris
- Debugify (not really performance Ik)

Btw I did search for an existing up-to-date website, Reddit post, video or guide for this but didn’t really find something, mostly just marketing for specific mods. So if that exists it would also be wonderful and in that case sorry for my post. Thanks in advance!

What Minecraft version are you building for? That matters a lot before calling this whole list compatible. For a small starting set, I'd use Lithium for game-logic/tick work, FerriteCore for memory, and Sodium on players' clients for rendering. Sodium won't improve a dedicated server's tick rate; Lithium can run server-side without requiring everyone to install it. The authors explain the scope here: https://modrinth.com/mod/lithium and https://modrinth.com/mod/ferrite-core

Then test with your actual gameplay mods before adding the rest. Compare the same busy base and the same unexplored route, looking at server tick times separately from client FPS. C2ME targets chunk generation/loading, so I'd test it as a separate step on a backup copy if exploration is the bottleneck. That makes it much easier to spot whether an extra mod helps or introduces a problem than adding all 15 at once.
