As a prerequisite, you have to understand how TCP flow control works, either from the basic RFCs or a TCP/IP networking text book.

A scenario, where the receiver throttles transmission speed would be, if ACK is delayed or even retransmission of segments is caused. I agree however with slacker, that you should try UDP for a fast transmission. Here you can immediately detect, if the transmitter is able to keep up with the data rate or possibly the receiver can't manage it.
