TCP can achieve performance in excess 1 Gbps on terrestrial links.  You
generally need to get to satellite links to have trouble and there the
maximum rate is around 1.5 Gbps over geosynchronous.

Just to be careful, as to specify TCP performance you need to say several
things: my statement is for a TCP with PAWS, SACK, and window scaling,
over terrestrial networks (delays < ~100ms) with appropriately low loss
rates.
