Everyone who is old enough to remember the sound of connecting to the Internet with a dial-up modem or of AOL announcing that "You've got mail" is acutely aware that there is an upper limit to how fast something can be downloaded, and it never seems to be as fast as we would like it. The big challenge is that we must strike a balance.
