title: Single Canvas and multiple panels vs multiple canvas in Unity 3D
body: <p>I'm developing a Holographic app for Hololens using Unity 5, I need to create some UI, so Which approximation would provide a better performance?</p>
  
  <p>A single canvas with multiple panels or multiple canvases?</p>
  
  <p>I need multiple UI elements (Text labels, buttons, etc...) with different locations specially with different Z axis values. </p>
