Hi! I am using Putty to login to my local server, but it takes about 1.5 seconds to login (from the click on 'connect' to working command prompt, most of time is spend on "Authenticating with public key...").

I know many see even slower speeds, but I would like to have not more than 0.1 login time.

I already set UseDNS=no and allowed only IPv4 in putty client and reduced key length from 4k down to 1k.

Any other suggestions to speed it further?
