title: D3 Map Pan and Zoom Performance on Chrome
body: <p>To make things easier, here is a <a href="http://jsfiddle.net/3twag6Lx/" rel="nofollow">JSFiddle</a> of what I have.</p>
  
  <p><strong>TRY</strong></p>
  
  <p>In FireFox (version 35.0.1) pan the map. Click and hold anywhere on the map, and move it about quickly left and right. Panning movement should be quick and smooth.</p>
  
  <p>Now try the same in Chrome and you'll see that it is not as smooth! It is a bit jerky/laggy. I find it laggy in the latest version of IE and Opera too.</p>
  
  <p>By the way, if you comment out this style block, then behaviour all of a sudden smooths out and stops being laggy! You won't get a nice map of course.</p>
  
  <pre><code>#map path {
      fill: #C9DCC9;
      stroke: #066860;
  }
  </code></pre>
  
  <p><strong>SO WHAT?</strong></p>
  
  <p>First of all I would appreciate it if someone can confirm this behaviour on their PCs. I am on Windows 8.1 with all latest updates.</p>
  
  <p>And then, why isn't this behaviour happening on other maps done with D3? <a href="http://techslides.com/demos/d3/d3-worldmap-boilerplate.html" rel="nofollow">This one</a> for example behaves smoothly! Is it to do with the complexity of the polygons?</p>
