Ditch Traditional JSON Parsing: Boost Spring Boot API Performance by 30×

A four‑month investigation revealed that Jackson’s default object‑mapper consumed over 60% of CPU time during order‑submission requests, causing 900 ms latency; switching to Jackson’s streaming API reduced average response time from 912 ms to 28 ms, cut GC pauses, and increased throughput eight‑fold, while introducing readability and validation trade‑offs.
