> 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.
