The Blocky, Modded Side of Lemmy
Rules: -Play nicely with others here
-Discussion should be at least somewhat related to modded Minecraft and all that entails
-Self-promotion is allowed within reason. Don't go overboard!
Sodium is the one with the most impact, but there are other good ones out there. So its not just one mod, but multiple. https://github.com/NordicGamerFE/usefulmods/tree/main/Performance

simply optimized modpack
I dont have ready list of performance improving mods but I would look at mods installed by rlcraft. The modpack is so heavy on resources they tend to add many mods for performance improvement.
I don't know about best, but give Fabulously Optimized a try.
