title: Knockout + large dataset performance
body: <p>I have a very large lat/long dataset which I'd like to be able to filter and display client side. I've profiled and optimised the best I can, but <strong>is there is anything further than can be done to speed up performance?</strong> </p>
  
  <ul>
  <li>Accuracy needs to be at the mile/kilometre level. </li>
  <li>I'd need IE 7/8/9/10 support although I'm accepting the further down we go the performance will likely get worse.</li>
  <li>I have not absolute dependency on any library, whatever is best for the job.</li>
  </ul>
  
  <p><strong>Roughly</strong></p>
  
  <ul>
  <li>Chrome: 1.1s </li>
  <li>Firefox: 0.9s </li>
  <li>IE10: 5.1s </li>
  <li>IE9: 3s</li>
  </ul>
