It maybe worth checking whether mfs is actually helping - it's easy to assume that because it's in RAM it must be fast, but I've had machines where mfs was slower than SSD (https://marc.info/?l=openbsd-misc&m=164942119618029&w=2), also it's taking memory that could otherwise be used by buffer cache. The main benefit to me from mfs is for things which I explicitly don't want to hit permanent storage.
