✓ 应当这么做
- ✓ Measure a baseline on realistic data before changing anything
- ✓ Fix the dominant cost first: network, then N+1 queries, then allocation
- ✓ Record the budget and the measurement method next to the code
✕ 常见反模式
- ✕ Optimising code paths not visible in the profile
- ✕ Micro-benchmarks that ignore cold start and contention
- ✕ Trading correctness for speed without an explicit decision record
◎ 交付前验证
- ◎ Compiler/interpreter warnings treated as errors for new code
- ◎ Test suite passes on the minimum supported language version
- ◎ Public API diff reviewed for accidental surface growth
