API Performance Optimization: Sub-200ms Automotive Data at Scale
· 9 min read
Serving 50 million monthly API requests for automotive data requires ruthless optimization. Our production API achieves p95 response times of 185ms while handling 5.8M daily requests—a 92% improvement from the initial 2.3-second average.
This technical deep-dive reveals the exact optimizations, architecture decisions, and code patterns that transformed a slow prototype into an enterprise-grade automotive data API.
