Most profilers show where time is spent — not why. Prompt Act as a senior performance engineer. Analyze this backend code and: – Identify hidden O(N) or O(N²) patterns – Flag unnecessary allocations – Suggest low-risk performance wins – Explain why each change improves performance Assume production load and real users. Why this works It […]
