TCP has well-documented failings on high-bandwidth, high-latency links. (referred to as LFNs (long fat networks) or "elephants"). The congestion and flow control algorithms in TCP are excessively conservative and end up massively under-utilizing the available bandwidth. Once a TCP connection has reduced its transmit rate (due to dropped packets indicating possible congestion), it requires successful packet receipts to increase its transmit rate (depending on latency).
