Some good treatment of the limitations and capabilities of TCP over  
high bandwidth-delay product paths can be found in RFC 2488. That  
document concentrates on satellite paths (i.e. high delay, modest  
bandwidth) but many of its conclusions and suggestions are equally  
applicable to high-capacity terrestrial paths (i.e. modest delay, high  
bandwidth).
