performance - Anyone have any opinions on DataTable.Load(DataReader) method? -

Does anyone have any ideas on this method? I have done some demonstration test on this and it seems to be performing poorly while doing data adapter. Then call or loop through the datesters and create new rows for the table. Do people use it in production, or is it just another thing Microsoft has given us that we do not use it?

Thanks

I use it in the output code, anytime due to it Have not seen poor performance

In the reflector it seems that they use both adapters. FillFromReader method, so I wonder why there is a difference performance? I do not care, it's a multi-threaded or something else.
