Most internet speed testing tools focus on bandwidth, but latency and packet loss are major factors in the experience as well.

Bandwidth means, once things get going, how fast you can download. But “once things get going” can take a really long time. In fact, it can take longer than the whole download! This is especially true for simple web pages, or web pages made up of a bunch of tiny pieces, which is very common on today’s web… That’s where latency comes in.
