You're right, the TCP peak was 1.48Gbps from the show floor in Dallas to a
storage cluster at Berkeley Laboratory. Single applications using multiple
stream. Bottleneck link was 1.5Gbps provisioned circuit on Qwest link from
convention center to DARPA's HSCC pop node.
This beat last years (SC'99) 1.2 Gbps rate Microsoft achieved running TTCP
on a single PC with 2 Gbit Ethernet cards (Redmond to Portland).
Peak rate alone is a meaningless measure of performance. The TCP session may
have reached peak for a small fraction of the session duration and the rest of
the time, the link may have been severely under-utilized.
A meaningful performance measure here is average or percentile link utilization
over the tcp session duration.
