There are multiple things in the mix:
  NetBSD version
  anita version
  anita hypervisor choice
    qemu vs xen, and version of chosen one
    if qemu, whether it is using nvmm

I am guessing you are using qemu unaccelerated.

I would try the old netbsd/qemu and the new anita.  I'd be surprised if
that made it really slow -- but if so that's good news as it's probably
easy to fix.

Then I'd try a netbsd 10 kernel on the same system, and if ok, a netbsd
10 userland.   FInally I would try a new qemu.
