title: Google Maps Freezing when zoom in/out
body: <p>I modify script from here <a href="https://stackoverflow.com/questions/30554435/add-label-overlay-google-maps/30560310#30560310">add label overlay Google Maps</a></p>
  
  <p>I just wanted to show some of the labels , not all.</p>
  
  <p><strong>code snippet:</strong></p>
  
  <pre><code>// LABEL /// 
  var label = new Label({ map: map, text: markerJson[i].kapasitas }); 
  if (markerJson[i].gardu != 'T') { 
      label.bindTo('position', marker, 'position'); 
  } else {} 
  // label.bindTo('position', marker, 'position'); 
  // LABEL ///
  </code></pre>
  
  <p>but when I zoom in - out, the map will error like freezing and marker will disapear.</p>
  
  <p><strong>result jsfiddle :</strong> </p>
  
  <p><a href="http://jsfiddle.net/o9dp8jhv/3/" rel="nofollow noreferrer">map no freezing + all label</a> </p>
  
  <p><a href="http://jsfiddle.net/o9dp8jhv/2/" rel="nofollow noreferrer">map freezing + some label</a></p>
  
  <hr>
  
  <p>and why if I load 1000++ data with label, map will lag, if just marker and infowindow map is fine. (I do not want to use map cluster)</p>
