title: WebAPI 2: is a void response faster then IHttpActionResult?
body: <p>I was building a method today in my WebAPI2. and came to the question if i should make my method a void or keep it as IHttpActionResult? </p>
  
  <p>As advantage i see that IHttpActionResult can return any response code. What is the advantage of the void approach? is it faster or is the only difference that it always response 200 (or is it 204?). </p>
  
  <p>Does somebody know which one is faster? or if it has any other major difference than the ones that i have named? (this includes the fact that void can't respond anything and IHttpActionResult can.......)</p>
