This paper describes the collection and analysis of a very large collection of delay data. The data is collected using the Turbo King method (recursive queries of Domain Name Servers). A model is given to fit the data. The data is analysed by continent.

It is shown that there is a strong relationship between delay and Haversine distance (the distance across the surface of the earth). However, this relationship breaks down in specific cases and occasionally, for some continent pairs, the opposite relationship is shown (longer distance is shorter delay).

This paper tries to establish the relationship between TCP throughput and fundamental qualities like round trip time, flow size and loss. The approach is data driven considering large numbers of publicly available data sources.
