what was the latency?  did you do any network debugging to see how
much traffic was moving between the terminal and fs?

the reason i ask is that at one point i had things miscofigured in
/lib/ndb/local and in the dns server that was serving my domain
so that even on a local gigabit network, startup took 10 minutes.
this wasn't due to network latency.
