ArcGIS Online - Tile Requests

[BrianRassier]

Hello -

Has anyone seen an issue with tile requests when using ArcGIS Online as an ArcGISTiledMapServiceLayer within the Map control?  We are seeing tiles get requested, and many are obtained in 1/4 of a second.  However, we also frequently get tiles that take 20-120 seconds for a response, creating blank tiles.  See attached which is from the WPF SDK Samples.

We don't see the same issue with ArcGIS Server services we have on site.  We also don't see the issue when using the JavaScript API to display these ArcGIS Online services.  Any thoughts?

We posted the "WebMarshal and Runtime" thread just before yours.

Yes we also experience patchy tiling - at times - and at other times it tiles fully. We have ESRI World Street Map and World Grey and both display this problem. We also have Bing 3 Layers - these are much faster and rarely if ever go patchy.

However, once we install on PC that goes through WebMarshal - both ESRI and Bing slow down appreciably - patchy tiling on both - sometimes total freeze.

This is just simple tiling actions - no queries/ searches/ routing etc.
