The classic lesson: one cross-region RTT costs more than a thousand RAM reads. Design the chain so far-away hops are rare and parallel.

Method

  • Composes a request chain from classic order-of-magnitude latency numbers.
  • Totals are arithmetic; the lesson is dominance — one expensive hop shadows thousands of cheap ones.
