Designing a minimal performance check

16 min · Module 18

Start small: script N iterations of a critical API, record latency distribution, fail CI if p95 regresses beyond budget. Avoid “tool theater” without baselines.

Example / notes

# Pseudo: hit GET /lab/api/health/ 50 times while logged in
# store durations; compute p50/p95; compare to baseline file

Practice in Lab: /lab/api/tickets/
