What is the significance of the b.N variable in Go benchmark functions?
- It represents the number of iterations in a benchmark.
- It indicates the number of available CPU cores.
- It stands for the total execution time of the benchmark.
- It is used to track memory usage during benchmarking.
In Go benchmark functions, b.N represents the number of iterations that the benchmark should run. It's crucial for benchmarking because it allows you to control the number of times a specific piece of code is executed, providing a basis for measuring performance and making comparisons. By changing b.N, you can scale the benchmark to get a more accurate performance measurement for different scenarios.
