A Primer on Speed. Discussing performance and “speed” can quickly get complex, because many underlying aspects contribute to a web-page loading “slowly”. It is physically limited by the speed of light or, practically, how fast signals can travel in wires or in the open air. also “only” take two round trips ((b) is rarely shown).
