title: Does interleaving in VBOs speed up performance when using VAOs
body: <p>You usually get a speed up when you use interleaved VBOs instead of using multiple VBOs.
  Is this also valid when using VAOs?</p>
  
  <p>Because it's much more convenient to have a VBO for the positions, and one for the normals etc. 
  And you can use one VBO in multiple VAOs.</p>
