title: vuetify list perfomance issue
body: <p>I have a simple json array which consist of object like this</p>
  
  <pre><code>{
      "kb:esid": "779256bf333d2d11abb52e39aafff20d",
      "kb:station": "Disco935 New York's Jammer",
      "kb:description": "Playing The 70's 80's 90's Disco And Beyond",
      "kb:station_url_record": {
          "kb:url_no": "1",
          "kb:url": "http://localhost/stream",
          "kb:status_code": "A",
          "kb:bandwidth_kbps": "128",
          "kb:url_strength": "9"
      }
  }
  </code></pre>
  
  <p>I use vuetify on codrova project to render list. The list consist of 3 lines: station, description and bandwidth. There is also a simple component to mark a station as a favourite. </p>
  
  <p>The list rendering takes about 5 seconds to render ~200 elements. I'm using a bit old smartphone: 2GB memory, 5.1 Android, ~1.2 GHz CPU. </p>
  
  <p>How can I increase the render speed? I tried to search infinity list in vuetify but there is nothing about it. </p>
  
  <p>Thanks.</p>
