The Transmission Control Protocol (TCP) drives major internet operations such as video streaming, file transfers, web browsing, and communications, accounting for very high percentages of fixed access internet traffic and even more of mobile internet traffic.

It is a widely held belief that web sites must be getting faster, rather than slower, thanks to the rapid evolution of browsers, devices, and networks. But is this actually the case?
