When uncached routes carry high bandwidth, check payload shape before recommending only cache headers. Fast Data Transfer includes the bytes transferred by requests and responses; compare compressed response sizes to the signal, not raw JSON.
Use bandwidthByCache, response size, and source serialization. Look for unbounded JSON, large embedded objects, static files through functions, missing pagination.
Do not shrink payloads without identifying fields or assets that are unnecessary for the route’s response.
Tie the finding to observed bytes, cache result mix, and the exact response line. A “large payload” claim must reflect post-compression bytes — the unit FDT meters.
