I'm trying out adding Primal Magick (4.0.9) to the All The Mods 9 modpack (Minecraft 1.20.1). Whenever I respawn after death client freezes up for good 15 seconds. Spark client profiling led me to 98.5% of the time being spent in ArcaneSearchRegistry.populate() (specifically in SearchRegistry.populate() which gets called from there).
This is likely only an issue in the presence of a lot of other recipes from other mods.
