title: What does "Optimize Code" option really do in Visual Studio?
body: <p>Name of the option tells something but what Visual Studio/compiler really do and what are the real consequences?</p>
  
  <p>Edit: If you search google you can find <a href="http://msdn.microsoft.com/en-us/library/k1ack8f1.aspx" rel="noreferrer">this address</a>, but that is not really I am looking for. I wonder the real things happening. For example why do the loops get less time, etc. </p>
