ActiveSharp and StackTrace speed

When implementing the StackTrace within ActiveSharp I did a few tests to check out the speed of the different techniques I could use to get the Property Name.

All the following times are for one million iterations.

Technique	Milliseconds
ActiveSharp	400
StackWalk	120000
MethodBase.GetCurrentMethod()	2000
"string"	20
const string	10

The speed of ActiveSharp is a little unrealistic because it caches the Property Name for each field in the class. A class with more properties or accessing many different objects would reduce the speed advantage.

Since the StackWalk was so slow I decided to check whether it was my code (examining the stack) or the creation of the stack in the first instance.

private void Button_Click_2(object sender, RoutedEventArgs e)
{
   DateTime start = DateTime.Now;
   for (int i = 0; i <= 1000000; i++)
   {
      StackTrace trace = new StackTrace();
   }
   DateTime end = DateTime.Now;
   MessageBox.Show(end.Subtract(start).TotalMilliseconds.ToString());
}

One million iterations took 118,000 milliseconds to complete. There is little point trying to improve my code further.
