Thank you for contacting Telerik support.
In JustTrace's toolbar in Visual Studio we have a button for Silverlight profiling (see attached picture). By enabling this option JustTrace will profile only the browser, where Silverlight is hosted, not the server side. This option can be used in both performance and memory sessions.
If the same behavior is still present, could you try to profile your application with JustTrace's standalone application and get back to us with the results.
Thank you for your time and cooperation.
