  <p>hello.</p>
  
  <p>Assuming usage patterns are the same (i.e. no negative numbers), which is preferable to use for various indexes, <code>int</code> or <code>size_t</code> type?</p>
  
  <p>Is there performance difference in your experience on 64-bit Intel between the two?</p>
  
  <p>Thank you</p>
