I humbly add that our experience with TCP supports this last statement
about achievable bandwidths.  The poor-quality TCP stacks in circulation
have left a widespread exaggerated bias that TCP is inherently slow. 
For a picture of a FreeBSD TCP stack running at 2Gb/s point-to-point,
see:

"Your mileage may vary."  Please, I don't want to start a thread on this
topic here.  This list gets quite enough traffic already, and the topic
has been beaten to death elsewhere (e.g., end2end).  E-mail any flames
directly to me: I am always happy to receive them!
