Understanding Prototype Pattern

I have a question regarding Prototype Pattern.

I read that Prototype Pattern is effective as it copies the object instead of creating a new one, which is considered as an expensive operation.

So based on this I tried a sample and I see varied results. Am I checking it in the right way Or have I missed anything?

class Program { static void Main(string[] args) { var sw = new Stopwatch(); sw.Start(); Employee e; for (var i = 0; i < 100000; i++) { e = new Employee(5, "sandesh", 27, "Bengaluru"); e.Print(); } sw.Stop(); Console.WriteLine("New : " + sw.ElapsedMilliseconds);

        sw.Reset();
        sw.Start();
        e = new Employee(5, "sandesh", 27, "Bengaluru");
        for (var i = 0; i < 100000; i++)
        {
            var en = e.Clone();
            en.Print();
        }
        sw.Stop();
        Console.WriteLine("Clone : " + sw.ElapsedMilliseconds);

        Console.ReadLine();
    }
}

public class Employee
{
    public int Id { get; set; }
    public string Name { get; set; }
    public int Age { get; set; }
    public string Place { get; set; }

    public Employee(int id, string name, int age, string place)
    {
        Id = id;
        Name = name;
        Age = age;
        Place = place;
    }


    public Employee Clone()
    {
        return (Employee)this.MemberwiseClone();
    }

    public void Print()
    {
        var sum = Id * Age;
        var full = sum + Name + Place;
    }
}

And the results are below: 1st Run:- New: 18 Clone: 26

2nd Run:- New:34 Clone:30

3rd Run:- New:20 Clone:33

Appreciate if you can help me out in understanding this pattern. Also what extra does it takes to Create a new object, which doesn't happens in cloning?
