How do I benchmark with realistic workloads?

        // Example of Go benchmarking function
        package main

        import (
            "testing"
            "time"
        )

        func BenchmarkMyFunction(b *testing.B) {
            for i := 0; i < b.N; i++ {
                start := time.Now()
                // Call the function you want to benchmark here
                MyFunction()
                elapsed := time.Since(start)
                b.Logf("Elapsed time: %s", elapsed)
            }
        }

        func MyFunction() {
            // Simulated workload
            time.Sleep(10 * time.Millisecond)
        }
