// MISSION BRIEF
Your Mission
Performance testing is where averages lie and percentiles tell the truth. This quiz covers workload modeling, the test types (load/stress/spike/soak), and reading latency distributions the way they actually behave under pressure.
// FIRST CONTACT
Battle teaser
Average response time is 200ms but users complain of slowness. p99 is 4.2s. The correct read:
- Ap99 is irrelevant if the average is good
- BUsers are exaggerating
- C1% of requests take 4+ seconds, averages hide the tail that users actually feel
- DThe average is wrong; recompute it
Answers, scoring, hints, and the full battle stay sealed.
