Explain how you would interpret and act upon the output of the go test -bench command when optimizing a Go program.
- Ignore the benchmark results; they are not useful for optimization.
- Focus on improving code readability and documentation.
- Analyze the benchmark results for execution time, allocations, and other metrics to identify performance bottlenecks.
- Only look at execution time; memory allocations are not important.
When optimizing a Go program using the go test -bench command, you should analyze the benchmark results carefully. The output provides valuable information about execution time, memory allocations, and other metrics. These metrics can help you identify performance bottlenecks and areas where optimization is needed. Ignoring the benchmark results or focusing solely on code readability/documentation will not lead to performance improvements. It's crucial to consider both execution time and memory allocations for effective optimization.
