I get really slow ssh connections on my z50, about 2 minutes to the
password prompt. Most of the time is spent in the handshaking.

Is this normal behavior? Once I'm connected everything is responsive at
normal speed.

I've done this via encrypted and non encrypted wifi. It also take a while
to get keys saved in ~/.ssh/known_hosts from a new server.

Have I set something up wrong or is this a limitation of the hardware?
