This is slow because you are copying the packet and shuffling
it in and out of Kernel address space. An NKE would be much faster.
I've written an NKE that does something similar (Ethernet Bridging)
to bridge packets from one data link to another. It wouldn't be
too hard to add multicast forwarding (or just use Ethernet Bridging).

NKEs are hard to write and debug, but there are samples you can get
from Apple. Is it worth months of effort? Or would you rather find
something close that can be adapted to meet your needs?
Kind Regards,
