Slowness probably depends on hardware as well as all the possibilities
listed by others. I have a model of router that always takes 2-3
seconds to initiate an SSH connection, just to set up encryption
(brief, but computationally intensive; happens with every connection).
10 seconds seems really slow, though. Smells like DNS.
