Citadel is responsible for a signifficant worldgen slowdown

After creating hundreds of modpacks, i was able to confirm via VisualVM and gameplay that citadel causes massive worldgenlag.
In some cases, i've seen over 50% slowdowns.
How to test it:
- Install a few hundreds of mods, citadel and one of it's supported mods.
- Use chunky to pregen the world with citadel and without it.
In my tests, i've seen worldgen with it go about 12-15cps, while without it's near 30cps on 1.18.2 and 1.19.2.
I'm willing to contribute with more information if the developer is willing to investigate it
Screenshot of the benchmark in a 300+ modpack in 1.18.2 with citadel, alex mobs and ice and fire:
In 1.16.5 there is also a slow-down, but it seems minor compared to 1.17+.
I'm reporting this in a constructive way for the author, since after 1.17 updates, mojang already shrewd up the worldgen performance by less than half.
