TL;DR: Performance testing isn’t “run JMeter and pray” 😄 It’s a set of test types, each answering a specific question: how fast, how much, how stable, and until when it breaks.

🔸 TAKEAWAYS (WHAT TO TEST & WHY)

▪️ Latency test → “How fast is one request?” (p95/p99 matter)

▪️ Throughput test → “How many req/s can we sustain?”

▪️ Load test → “Are we OK at expected peak traffic?”

▪️ Stress test → “What’s the breaking point + recovery?”

▪️ Endurance test → “Any leaks / slow degradation over hours?”

▪️ Capacity planning → “How many users per node? how much infra?”

▪️ Degradation test → “If DB/cache/3rd party is slow, do we fail gracefully?”

🔸 CONCLUSION

Pick the test type that matches your risk: speed, scale, stability, or resilience. One tool, many goals.
