Jason,

We have tracked down the source of the major delays we are seeing, it's when
the TDatasetProvider.CreateDataPacket -> TDataPackerWriter.GetDataPacket ->
TDataPackerWriter.WriteMetaData -> TDataPackerWriter.AddIndexDefs routine
calls the IProviderSupport(Dataset).PSGetIndexDefs([ixUnique]). This
statement alone accounts for 95% of the performance differential.

We did have an initial look at the Conversion Guide, we will do so again.

Thanks

Sean
