Been investigating this in the 1.20 alpha. It's an algorithmic issue - permafrost is generated in "blobs" similar to underground clay, but because the blobs are very large and there's tons of them, the game spends a lot of time in the blobs code.

You can resolve it by turning down the "horizontal size" of permafrost in the config file (set it to like 15) and increasing the rarity. Of course, it will make the blocks less common, but they're already very common I think.

We're considering changing this to a noise field instead of using blobs.
