Day 2: Your First Baseline
Objective
Run a single-user loop for 5 minutes and capture min / avg / p90 / p95 response times.
Scenario
Run the same script for 5 minutes with 1 user looping continuously. Export or screenshot your results summary.
Metrics to Watch
When It Clicks
The 'average' lies; p95 tells the real story.
Solution
Set the Thread Group to 1 user, loop count = forever, duration = 5 minutes. Add a Summary Report or Aggregate Report listener. After the run, screenshot or export the table showing min, average, p90, p95, and max columns. The gap between average and p95 is your variance fingerprint for this endpoint at zero concurrency.
Reflection
How much higher is p95 than the average? What does that variance mean?
Deliverable
A baseline results summary you can compare against later.
⚠️ Never run load tests against infrastructure you do not own or have explicit written permission to test. Always use a dedicated test environment. Unauthorized load injection can cause outages, trigger legal liability, and violate terms of service.
