MAP Rendering very slow in arcgis api for silverlight 3.0 using MS Silverlight 5.0

[ATTACH=CONFIG]14200[/ATTACH]Hi,

Recently in one of my new projects with ESRI SL API 3.0 (ArcGISSilverlight30_prerelease.exe) Silverlight 5, I found that the map was rendering very slow as compared to the same project compiled earlier with ESRI SL API 2.4 and MS Silverlight 4.
The Map contains ArcGISDynamicMapServiceLayer with labels enabled from MXD level. In the new project the Labels as well as the map data both are rendering very slowly in some situations of zoom in and out. Though in the earlier project it was not the same.
Also the new project does not have any code change as compared to earlier project source.

If I am missing something here please guide,help for any new changes required for projects in the new version of the ESRI SL API 3.0.

Thanks,

Is this the same service as before, or have the service also been upgraded?

Yes the REST service (from production server AGS 10.0 SP2) is the same, nothing changed since it is serving the old live project build (ESRI SL API 2.4, MS SL 4.0) as well.

This is very strange.
Is there any chance you could have two apps running side-by-side: One that runs 2.4 and the other 3.0, then have Fiddler running and see if the requests that are sent to the server from the two apps are any different?

Thanks , I tried to exactly as you asked me. But I failed to notice any differences between the two application requests to the gis server. The service requests for same zoom in/out operation for same location on map, from both the application instances looked same in fiddler in terms of columns - results and body and in statistics.

Thank you for trying that. Is there any chance you can send me a repro? (mnielsen at esri)
