I'd like to know typical round-trip times on networks in order to determine whether or not they will be the limiting factor in the latency of a whole application. Measuring it on a laden 100Mbps network here I get 95% of pings under 500µs with a median of 400µs.
What are typical latencies on unladen networks and how does the bandwidth spec (e.g. 1Gb, 10Gb) of the network affect the latency?
