title: Speed up autocomplete suggestions
body: <p>I have a script which uses ajax(json) to fetch Google suggestions(xml), demo: <a href="http://jsfiddle.net/Xbpk7/8/" rel="nofollow">JsFiddle</a></p>
  
  <p>I think it reacts to slow, especially on the first keyup. So I want to speed it up. I first thought of doing the request on keydown instead of the default keyup. But that didn't speed it up and caused another problem; it was not possible to come down in the list anymore. So my question is: Is there any way of speeding up the first keyup(suggestions), and maybe the whole thing all together?  </p>
