title: why is .net 2.0 faster then 4.0
body: <p>I wanna test my computers performance
  so I ran this code</p>
  
  <pre><code>public partial class Form1 : Form
  {
      public Form1()
      {
          InitializeComponent();
      }
  
      private void button1_Click(object sender, EventArgs e)
      {
          DateTime dt = DateTime.Now;
          Int64 i = 0;
          do
          {
              i++;
          } while (dt.AddSeconds(10) &gt;= DateTime.Now);
  
          this.textBox1.Text = i.ToString("n0");
      }
  
  
  }
  </code></pre>
  
  <p>when I select .NET Framework 2.0 I get a result of 33 Million
  but when I select 4.0 I get only 9 Million</p>
