Using DesktopEdition 4.5, we notice the first time we render a map using the World Map Data Kit it takes about 30 seconds to display the map. During that time, there is significant disk I/O happening (visible via perfmon). Later renders of the map, even after stopping and restarting the application, do not take long at all (< 5 seconds). After the machine is rebooted, the first load will again take > 30 seconds.
Any idea why? I can understand reading the data from the shapefiles, but I'd like to understand what is happening the first time the map is loaded after the machine boots that is different from subsequent loads of the control.
Thanks for any insight,
