It's worth noting that as pipes get bigger and faster, caching
assumes a greater, not lesser, importance. Higher bandwidth
and constant latency means a greater bandwidth-delay product,
and a corresponding degradation in performance. Caching is
just as much about local replication to reduce latency as it is
about "conserving bandwidth."
Particularly when a large proportion of the stacks out there perform
very poorly under the prevailing conditions in today's Internet with
its medium-to-high, jittery latencies and occasional to frequent
packet loss (cough, cough, Redmond, cough). Far better to use a proxy
on a platform like BSD that at least doesn't have an egg-sucking TCP
implementation.
