C2ME-fabric VS lazydfu

https://github.com/RelativityMC/C2ME-fabric add this

I like custom textures but so many of them require OptiFine. I already have a bunch of OptiFine alternatives. I have Sodium, FerriteCore, C2ME, LambDynamicLights, Starlight, and Sodium Extra. I have looked at Animatica but that only allowed for animated textures. Do you guys know of any mods that allow for OptiFine textures but work with my performance mods?

1) LazyDFU: Compiled DFU rules afterwards. 2) EntityCulling: Doesn't render entities that you can't see 3) NoFade: This isn't exactly a performance mod, but fading sometimes makes my game crash, so I use this. 4) NotEnoughCrashes: Again, not a performance mod, but makes crashes much easier to handle. 5) SmoothBoot: Makes Minecraft not hog too many resources when starting up 6) SodiumExtra: Basically adds more options to Sodium. 7) Hydrogen: idk how to describe this (I no longer don't use this as 1.18 hasn't released yet, but I'll this in anyway). 8) C2ME: Improves chunk performance. 9) Enchanced Block Entities: Improves rendering of block entities. Note that this only really shows effect when you're in an area with tons block entities (eg. your storage basement)

It's a bit dangerous and I wouldn't exactly recommend it because I haven't tested it, but there's C2ME. It's VERY experimental. Doesn't exactly do what you're saying, but it should help. I recommend using this list for reference on fabric and forge performance mods, both server and client side. It's very useful.

C2ME. Massively improves chunk loading by multithreading it

Mods (Fabric modloader) used in this video: Sodium, Lithium, Starlight (Beta), C2ME (Alpha), EntityCulling, Hydrogen, LazyDFU, Krypton. You can replace Sodium with Iris for shaders.

You don't need to redesign the server. You can just use these mods.

From LazyDFU's github repo:

LazyDFu v0.1.2

I would suggest you to use Sodium or Iris - Overall Performance Improvement / Iris If You Wanna Use Shaders Too Lithium - Improve CPU Usage LazyDFU - Launch Game Faster Phosphor - Improve Light Engine Hydrogen - Reduce Memory Usage

I'd recommend checking out some of the mods in the fabulously optimized modpack. Most notably I'd recommend LazyDFU, No Fade, and Smooth Boot as they're most applicable to the problem you're describing.

(Experimental) Lazydfu ( astei/lazydfu )

You could try installing Hydrogen and LazyDFU t see if they do anything for this. Hydrogen will reduce Minecraft's Memory usage, which should help with the GC pauses slightly. LazyDFU will improve startup times and reduce the massive amount of garbage from DataFixerUpper during startup (Mojang's backwards compatibility system), which might also improve things during gameplay as well.
