> Send 1KB over a 1GBps network

This is said to have a 10μs latency in the chart. But I'm fairly sure that is a calculation of bandwidth based on 1KB / 1GBps

10μs is about 3Km, so at most a 1.5Km round-trip.

For a chart labelled latency, I'm surprised to see bandwidth calculations included. Any network hop would actually have far greater latency, if nothing else because communication typically involves more than a single round-trip for acknowledgement, etc.

It might be worth making it clear some of the numbers are about bandwidth not latency.

Fair point! Will update! I think the focus was on pure line latency. Check out the more detailed post here. https://gist.github.com/jboner/2841832
Distance is of course a factor, but at fixed distance size matters a lot, and most applications are at more or less a fixed latency.
