Latency is a key limiting factor on the web: given that most assets fetched by webpages are relatively small (compared to, say, downloading a software update or streaming a movie), we find that most experiences are latency-bound rather than bandwidth-bound. The speed at which files download will be a function of bandwidth and round trip time.
