Stab in the dark, but have you verified you don't have a duplex mismatch anywhere? IME, they can look exactly like that.

I seriously doubt you'd be able to get 30 megabit/s over somewhere with a duplex mismatch. My testing was done 7-8 years ago so things might have improved regarding TCP congestion algorithms, but I doubt it'd make that much of a difference. My experience is/was that with a duplex mismatch and 10 or 100 megabit, you seldom got more than around 2 megabit/s of effective throughput using TCP.
