title: How is Array.Sort in C# so super-fast?
body: <p>Hey, I have been trying to find an answer (both on stackoverflow and google) to the question how Array.Sort in C# is so fast.
  I didn't find one.</p>
  
  <p>No matters which algorithm I used I didn't manage to sort big arrays faster than it.
  I know it uses Quick Sort, but it must be very optimized.</p>
  
  <p>Does anybody know how did they make it so fast?</p>
