I very much doubt that that is an artifact of TCP. I can go from nothing to 10gbit/s symmetric in 100->200ms when running Iperf3 over TCP against another one of my LAN hosts.

And, back when I had a 1.5gbit/s Internet downlink, it took far, far less than 20 seconds to reach > 500mbps for big Steam downloads and other such well-provisioned things.
