Description:
Whenever chunks are generated, there is a significant hiccup any time there's a waystone that has to be generated. When I disabled waystones from spawning in the world, the chunk generation speed doubled using the Chunk Generator mod.

I also have towers_of_the_wild-1.16.4-2.0.1, which I have seen cause lag when generating. I saw a cross section of a tower on the edge of a chunk, with most of it (including the waystone) in a chunk that hadn't generated and took quite a long time to appear.

Here is a spark profile, which clearly shows the waystone mod is causing lag: https://spark.lucko.me/pTErP2y0Xh

Do you use any performance-enhancing mods (e.g. OptiFine)?

performant-1.16.2-5-3.72m

This also happens to me...
