I have a very simple page built to display a map and overlay a line based on points in a GeoRSS XML file. Here is the publicly accessible file. http://68.178.230.189/georssimport.html

Firefox is loading in about 5 secs, which is expected because there are a lot of points to map, but IE (6 & 7) is taking upwards of 45 secs to a minute. What can I do to diagnose what is going on? What is a tool that will show me what is going on? (i.e. Firebug for IE)

Thanks, Mark
