“Present efforts at reducing latency, nevertheless, fall far short of the lower bound dictated by the speed of light in vacuum. What if the Internet worked at the speed of light? Ignoring the technical challenges and cost of designing for that goal for the moment, let us briefly think about its implications.”
Summary: the speed of the Internet is still far from the theoretical limits, specially when it comes to #latency.
The most interesting part of the paper is the measurement of the things that take time when connecting to a Web site: latency often dominates (unlike what the ISP ads “100 Mb/s!!!” say).
