Sample Answer
When I saw a REST API with wildly inconsistent response times at my last role (p95 spiking from 120ms to 2.5s for ~150k daily requests), I treated it like a three-tier detective job. First I validated the client: Chrome DevTools and synthetic tests to confirm whether total time was network vs rendering; I checked bundle sizes and cached assets and saw no frontend-induced spikes. Then I instrumented the app server with APM (New Relic) and distributed tracing (Jaeger) to measure p50/p95/p99 per endpoint and discovered long controller-to-service times. From there I checked DB metrics (pg_stat_statements, slow query log, CPU, I/O, active connections) and found a few queries doing sequential scans under load. I added query plans, introduced indexes, raised connection pool from 50 to 120, and put a 60s cache on high-read endpoints. Within two weeks p95 stabilized from 2.5s to 180ms and error rate dropped 70%.
