Report Data Definition maintenance is VERY slow

Is it normal that RDD maintenance is really really slow? Or could this be a symptom of some other issue?

Loading a record (even an original unmodified RDD) can take 30 seconds or more.

Running the trace shows, that Ice.Proxy.BO.RptDataDefImpl.GetDataDefUsedTables is called 3 times with each call taking 7 - 10 seconds

Just changing between Tables in the Table list can upwards of 10 seconds

Is this anything to be worried about?

Yup, perfectly normal (unfortunately)
