Correct. While simple, this does have the performance impact you're alluding to. On my 20mbps (down) connection, I peak out at 16mbps on subnet.

The 'double congestion-control' effect can be alleviated by opening 10 or so TLS connections and pumping the packets down those, to spread the effects of TCP congestion control.
