Comment 5 for bug 1638537

Until the device key is generated there is nothing it _can_ do (in fact it might not even be listening to requests yet; not sure offhand). That said, on the pi2 it takes a little over a minute to do the keygen (and that's too long, but not much we can do about it without better hardware support for vector multiplication), so you should be seeing times significantly shorter than that.

Would you be able to build a profiling snapd and do a first boot with that?
