What happens during the Benchmark stage after code analysis with linters?

After the code has been analyzed with linters, the Benchmark stage in Go typically involves measuring the performance of specific sections of code. This is done using special performance tests (benchmark tests), which are run through go test with the -bench flag.

At this stage, the following occurs:

• Measuring the execution time of functions or methods.
• Assessing resource usage (e.g., memory allocations).
• Comparing different implementations to select the most efficient one.

An example of a simple benchmark test in Go:

func BenchmarkSum(b *testing.B) {
    for i := 0; i < b.N; i++ {
        _ = 1 + 2
    }
}

Run:

go test -bench=.

Thus, Benchmark helps identify bottlenecks in performance and optimize the code after it has been checked for style and errors by linters.
