- Dominant cost
- TLS handshake55% of total
- Budget left
- 94.5 ms
- Verdict
- Within budget
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.
