title: jQuery /hover()/.mousemove() optimization issue
body: <p>I'm working on a basic modal example in which the modal would follow the mouse cursor as long as the user was hovering over a certain section.</p>
  
  <p>The issue I'm having is, when going from left to right, the modal lags significantly, as well as triggers the fadeOut() set if the user were to mouse out of the specific section.</p>
  
  <p>Right to left, works seamlessly. </p>
  
  <p>In the fiddle, you can observe the lagginess when moving the mouse over the <code>&lt;nav&gt;</code> from top to bottom, as well as notice the solid performance from bottom to top.</p>
  
  <p>If there are any duplicate questions or related articles that you all know of, please point me in the right direction. My searches thus far have been informational but have not adressed this specific issue.</p>
  
  <p>Here is my <a href="http://jsfiddle.net/bxLPh/15/" rel="nofollow">fiddle</a>.</p>
  
  <p>Thank you all, as always pro advice is warmly welcomed.</p>
