What is performance testing and what should QA measure?
Answer
Performance testing measures speed and stability under load.
Measure:
- Latency percentiles (p95/p99)
- Throughput
- Error rate
- Resource usage
Use realistic scenarios and ramp patterns. Performance issues often come from DB bottlenecks, N+1 queries, and missing caching.
