title: How to improve KML performance
body: <p>Hi
  I'm having some issues with KML performance. At some times the KML markers only appear after a reload which may have to do with google caching the results. I think a better solution is needed perhaps something like displaying a total of markers for an area on a larger zoom level and then more detailed for levels that have more zoom. Is such a solution feasible and if so, how? Can you think of other ways how I can improve performance of my KML map? The links are <a href="http://www.koolbusiness.com" rel="nofollow">http://www.koolbusiness.com</a> and the KML file is <a href="http://www.koolbusiness.com/list.kml" rel="nofollow">http://www.koolbusiness.com/list.kml</a></p>
  
  <p>I can load the KML file into maps.google.com with no problem however when trying to display it on my custom map the display sometimes won't load.
  Thanks in advance for any suggestions.</p>
  
  <p>UPDATE: I've updated to using a KMZ file with zip compression. The file is available via <a href="http://www.koolbusiness.com/list.kmz" rel="nofollow">http://www.koolbusiness.com/list.kmz</a> and the source and more info is available at <a href="http://montao.googlecode.com" rel="nofollow">http://montao.googlecode.com</a></p>
