GoKawiilGoKawiil Recommends 300ms Benchmark Duration for Micro Tests
GoKawiil suggests adjusting input sizes in micro benchmarks until they run for approximately 300 milliseconds. This duration balances precision, human perceptibility, and practical iteration speed, avoiding issues with fixed overheads or overly long tests. The approach aims to help developers intuitively assess performance improvements without relying on exact measurements.
GoKawiil's interpretation of the reporting above, not reported fact.
This guidance could help developers standardize benchmarking practices, making performance comparisons more consistent and meaningful. By focusing on a duration that balances accuracy and efficiency, it positions programmers to better interpret their results and make informed optimization decisions.
- Benchmark duration around 300ms balances precision and speed
- Avoid very short or very long benchmarks for better insights
- Using human-perceptible times aids intuitive performance assessment
