Thanks for the advice.
Do you have spare network interfaces? You could spin up another interface with a new IP and try copying via that path:
snapmirror initialize -S filer:/vol/a filer-eth1:/vol/a_new
That might be faster than the loopback. But I wonder if the real issue is come other bottleneck. Are the new volumes/RGs on different fibre channel controllers as well?
