If I understood you correctly, then the first thing to look at is simply... pings to the other side, to see how much actual network latency and/or drops you have. If I understood you incorrectly (and everybody else understood you correctly), then I would add to everyone's suggestions, this: take a look to see if you have avahi-daemon running. This little creature have a tendency to cause session setup delays, even with all DNS off... if you do have it, take it off if it's not needed (and it probably isn't...) HTH, -- Shimi
