Deforming geometry increases pyro sim time?

Hello, everyone

A simple question, it's basically the title. By "increase" I mean increase by a lot. Everything the same, just turning on "Use deforming geometry" increases the sim from 60 frames in around 8 hours to 7 frames in the same time

From what I could see it really takes a long time in the "creating collision mask" (or something of the sort) step. I have the VDB of the colliding object already cached in a SSD. So, is this normal?

Also, a side-question, when you use a static object in DOPs, does it use the Bullet Solver or the RBD solver by default? I'm sure I saw this question here before, but unfortunately I can't find it
