How to speed up TextField input?

Hi,

I've got a TextField that I'm trying to work with in a GUI. However, the displaying of the text is terribly slow. Using the following code, I have verified in the console window that the characters are indeed being received, but the actual display of the text is not occurring until 3-4 seconds after I finish typing. Any thoughts as to how I can speed up the process?

 String m_test = "";
 
 public override void OnGUI()
 {
   String tmp = m_test;
   tmp = GUI.TextField(new Rect(0, 0, 300, 22), tmp);
 
   if (tmp != m_test)
   {
     m_test = tmp;
     Debug.Log("m_test = " + m_test);
   }
 }
