High CPU usage

Question

Hi All,

In a test map, with nothing but an ArcGISTiledMapServiceLayer in it, the CPU usage meter shoots up to nearly 100% (on a dual core machine) when the extents change and the tiles are downloaded.  once the tiles are downloaded, the CPU drops back down to 0.   i notice that this spike doesn't occur in the sample app http://resources.esri.com/help/9.3/arcgisserver/apis/silverlight/samples/start.htm#Map<esri:ArcGISTiledMapServiceLayer x:Name="Base_Map" ID="Base_Map" Url="http://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer"/>

the culprit seems to be any containers on top of the map that have an opacity below 1.  i'll call this resolved, and a silverlight issue not an ESRI API one.
