Response time dropped from 1200ms → 120ms.
I always thought caching was the biggest performance booster…
Turns out, I was completely overlooking something much simpler.
After reducing my API response size by 80%, the performance improvement was insane — nearly 10× faster responses.
In this article, I break down:
- Why large payloads silently kill performance
- The exact mistake I was making in Spring Boot
- How I fixed it with a simple change
- Real before vs after impact
If you're working with Spring Boot APIs, this might save you hours of optimization work.
