"WebFor example, consider a situation where a user wants to fetch a 1-MB file across a 1-Gbps with a round-trip time of 100 ms. This includes both the transmit time for 1 MB (1 / 1 Gbps × 1 MB = 8 ms) and the 100-ms RTT, for a total transfer time of 108 ms. This means that the effective throughput will be. 1 MB / 108 ms = 74.1 Mbps. not 1 Gbps. " - Round trip propagation time
