Load Testing · Senior · Question 45 of 76
Why should load test results be reported per time window as well as for the whole run?
- 1Per-window data is required by every load tool licence
- 2A clean overall p99 can hide minutes that broke the SLO
- 3The overall p99 is always larger than any window's
Show the answer
Correct answer: A clean overall p99 can hide minutes that broke the SLO
Explanation
SLOs are often measured per window. Ten bad minutes in an hour can blow an error budget even if the hour's p99 looks fine.
