How do I benchmark logging overhead using slog in Go?

In Go, to benchmark the logging overhead using the slog library, you can create a simple benchmark test that measures how long it takes to log messages of varying levels and complexity. This will help you determine the efficiency and performance impact of using slog in your application. Below is an example of how you can implement logging benchmarks using slog.


    package main

    import (
        "testing"
        "github.com/go-stack/stack"
        "github.com/slog/slog"
    )

    var logger *slog.Logger

    func setup() {
        logger = slog.New(slog.NewJSONHandler(os.Stderr))
    }

    func BenchmarkSlogInfo(b *testing.B) {
        setup()
        for i := 0; i < b.N; i++ {
            logger.Info("This is an info message", "depth", stack.Call(1).Function)
        }
    }

    func BenchmarkSlogError(b *testing.B) {
        setup()
        for i := 0; i < b.N; i++ {
            logger.Error("This is an error message", "depth", stack.Call(1).Function)
        }
    }
