To Reproduce:
Steps to reproduce the behavior. Format it as a numbered list of steps.

Expected behavior:
Game Should Load Minecraft Chunks Fast And Normal
I've also been getting generation lag, but just looking at the console for me, it would seem it might be because the game is trying to place features in faraway unloaded chunks and is erroring.
those error messages are unrelated to the chunk lag. The lag has been fixed in the dev version and will be available in the next released version
The main reason I am posting this as an issue, is not because it effects single player, if anything its not that noticeable, the issue is the performance is even worse on servers with more than 1 person. Sometimes even completely unplayable.
I know this is a known issue, but I experienced this too and I found the root cause. It looks like FastNoiseLite.GetNoise()(lol) is mainly causing the performance drop, along with minecraft's LevelReader.getBiome().
Here's a spark profile of the offenders. Hope this helps, I like the mod!
Yeah I was having this issue on my server too. Although I couldn't get a spark profiler to give much info, I made a replica server and used chunky to keep generating the same seed, so I had a constant to test against.
Just the plain fabric 1.19.2 install with no mods would generate 35 chunks per second. With all my mods, that dropped to 9 - 12 chunks per second. Once I disabled spelunkery's worldgen in the config, it jumped up to 19-24 chunks per second.
