In the release notes for defect #602, you mention that "Retrievals are very slow, however, when the DataRowState parameter is set to DataRowState.Deleted. This is a known performance issue and will be addressed in the next release."
I have just waited over 7 minutes for GetEntityGraph to return from querying a root entity with 75 children. This is with the application built in release mode and running on a dual-core machine with 2 Gb RAM. Debug mode is completely unusable.
I appreciate that it now "works" (in that deleted entities of non-deleted children are now returned), but do you have any idea when you'll be able to optimize it?
