Forcibly de-tuned the benchmark to make Chrome spit out a marginally representative result.

Preparation HTML

<script>
  var medium = new Array(100).join(" ' "),
      large = new Array(1000).join(" ' "),
      xtralg = new Array(10000).join(" ' ");
  
  function createSmall() {
   return " ' ' ' " + Math.random();
  }
  
  function createMedium() {
   return medium + Math.random();
  }
  
  function createLarge() {
   return large + Math.random();
  }
  
  function createXtralg() {
   return xtralg + Math.random();
  }
