MC-239794Generation with noise_caves enabled is noticably slower
The Bug
Having noise_caves, found in noise settings, enabled increases generation time by a lot.
This can be seen as continuation of MC-217509 which is now fixed but didn't fix all issues noted in the report. my fault, one bugreport shouldn't contain multiple issues.
To note that in MC-217509 noise_caves weren't the major slowdown, which they are now.
I got this data with a script that generates each custom world settings file 5 times and outputs the time it takes. The raw data from each time generating can be found in 21w42a-results.txt
Reproduce + Observed Result
Generate and compare the time it takes to generate a world with each custom world config.

21w42a-noise_caves_enabled.json
average: 61.800010824203 seconds

As you can see in the data, generating the custom world that enables noise_caves takes a lot longer than with it disabled.
Expected Result
Noise cave generation is a feature that is expected to take some resources and time, but the amount of time it takes right now is a lot and would preferably be a lot less.
Created Issue:
noise_caves generation takes long / inefficient
Having noise_caves enabled in noise settings greatly increases generation time.

Can confirm
Yes, enabling more features affects performance.

I think someone forgot to read it. I agree, it looks like noise_caves are taking up more resources than planned. If in 1.17 enabling this setting added +2-5 seconds of time for generation, now generation slows down by 4-12 seconds because of this. Even aquifers don't slow down generation like that.
