Latency budgets for B2B SaaS
Why p95 matters more than p50 when procurement reads your SOC deck.

- Auth handshake and token refresh
- Search and list endpoints behind the heaviest tables
- File uploads and virus-scan hooks
“If the demo feels slow, the architecture review starts defensive.”
Ship a one-page latency budget with owners per surface. Finance understands owners.
