How do I benchmark logging overhead using standard log in Go?

Benchmarking the logging overhead in Go is a useful practice to understand the performance impact of logging in your application. The standard `log` package in Go makes it easy to measure how much time is spent logging messages.

In the following example, we create a benchmark function that logs a message several times and measures the time taken to complete the logging operation.

package main

import (
    "log"
    "testing"
)

func BenchmarkLogging(b *testing.B) {
    for i := 0; i < b.N; i++ {
        log.Println("This is a log message.")
    }
}
    

This simple benchmark will help you gauge the performance overhead associated with logging operations based on the number of iterations specified by the testing framework.
