Performance · interview question
A teammate submits shaky microbenchmarks code. Which review comment is the strongest?
Multiple choiceEasychapter-16-curatedpremiumperformancemicrobenchmarks
Answer and explanation
Correct answer
B. Make the rule clearer and easier to explain. Use small timing comparisons carefully and avoid treating them as proof of whole-system improvement.
Why
The best review comment anchors the change to readability, correctness, and future maintenance. A faster microbenchmark can still be irrelevant to the end-to-end user experience.
