Right

        System.Diagnostics.Stopwatch s = new System.Diagnostics.Stopwatch();

        Console.WriteLine("Test1: {0}", s.ElapsedMilliseconds);

        s.Reset();

        s.Start();
        for (i = 0; i < count; i++) Test2();
        s.Stop();

        Console.WriteLine("Test2: {0}", s.ElapsedMilliseconds);
