Section 3 Review
You've finished Executing Performance Tests, the third section of Performance Testing. This page is a dedicated recap — bookmark it as a fast reference, separate from the modules themselves.
Section Summary
✔ Performance Testing Tools — the four concepts every tool implements (virtual users, request scripts, timing, metrics), mapped onto JMeter as this path's primary worked example, not the canonical tool ✔ Executing Load, Stress, Spike, Soak, and Volume Tests — the specific, distinct ramp-up and duration configuration each test type actually requires ✔ Bottleneck Analysis and Monitoring — correlating a load timeline against resource-utilization timelines (CPU, memory, database, network) to identify the actual constraint, not just that something degraded
How they build on each other: Module 7 gave you the concepts a tool implements, independent of any specific tool. Module 8 turned those concepts into distinct, deliberate configurations per test type. Module 9 closed the section by turning a test's raw results into an actual, correlated finding — the difference between "it got slow" and "it got slow because of this specific resource."
Section 3 Quick Reference
| Question | What to Do |
|---|---|
| What does any performance tool need to do? | Simulate virtual users, run a request script, control timing, capture metrics |
| How is a stress test configured differently from a load test? | Incremental steps past peak, continuing until a breaking point is found |
| How is a spike test configured differently from a load test at the same peak? | Near-immediate ramp-up, not gradual |
| How do you find what actually caused a performance degradation? | Correlate the load timeline against CPU/memory/database/network timelines |
Section 3 Knowledge Check
Five realistic scenarios. For each, decide which module's framework applies. No answers are provided here. Solutions: Section 3 Solutions.
Scenario 1: A teammate insists JMeter is "the" performance testing tool and dismisses a proposal to evaluate k6 for a new project.
Scenario 2: A "stress test" report shows a single test run at one fixed load level that passed, with no further load increase attempted.
Scenario 3: A load test shows response time degrading, and memory utilization climbing steadily at the exact same moments, while CPU and database connections stay comfortable throughout.
Scenario 4: A test needs to measure how fast a system reacts to a sudden traffic surge, not its behavior under gradually increasing traffic.
Scenario 5: A performance report says "the system was slow under load" with no other detail.

Analysis and Operations, starting with Result Analysis and Reporting — where this section's bottleneck findings become a communicated, actionable result.
