Latency vs bandwidth: why a faster plan can't speed up a small page

Networks · 5 min read ·

You upgraded to a much faster internet plan, yet a small web page loads just as slowly. Why? Network speed is two different numbers: bandwidth (how much data flows per second) and latency (how long one message takes to travel).

A page needs several round trips just to start, and light in fibre cannot beat distance. Drag a server around the world and see where the time really goes.
