Stop Using JSON Blindly: How Switching One API to MessagePack Cut Response Time by 5×

A performance bottleneck hidden in a fintech dashboard’s “coffee‑time” API was solved by profiling, discovering that 85% of latency came from JSON serialization, and replacing it with MessagePack, which reduced payload size by up to 74% and slashed end‑to‑end response time from 847 ms to 159 ms—a more than five‑fold improvement.
