Light Reading mentions S2io cards doing 7Gb/s
(http://www.s2io.com/news/news/lightreading_031020.pdf).  I've seen a
pair of these cards exceed 7Gb/s and approach (but not reach) 8Gb/s in
a demo setting (with machines running back-to-back).

SC 2003 bandwidth challenge shows some impressive results
(http://scinet.supercomp.org/2003/bwc/results/).  These are over WAN,
not back-to-back.

The current Internet2 land speed record in the single TCP stream
category is 5.44Gb/s, or 38 petameter-bits per second, taking the
distance, 7067km, into account (http://lsr.internet2.edu/, OS/hardware
details at the history link).

(Many of the people who did these tests are on this list, too.)

Were 1500-byte frames used?  That would be about right then.
