Load Testing · Senior · Question 35 of 76
A service adds batching: throughput doubles, p50 grows. Is it a regression?
- 1No: higher throughput always means lower latency
- 2Yes: any increase in p50 is always a performance regression
- 3It depends: latency is traded for throughput, check the SLO
Show the answer
Correct answer: It depends: latency is traded for throughput, check the SLO
Explanation
Batching waits to group work. That can be fine for background jobs and bad for interactive calls. Judge against the requirement.
