My gut instinct says this is an end-to-end latency issue. Bits of my brain
(that I laughingly refer to as the common-sense bits) say that several hops
each with a small end-to-end latency will perform better than a long-haul
connection, even if the total latency on the long connection is slightly less
than the sum of the smaller hops.

So long as the machines at each hop are not bottlenecks in and of themselves.

This is especially apparent as the link bandwidth narrows towards the
retriever.
