Faster (more scalable) DataSet.Merge?

Question

We use strongly typed DataSets in our application. When importing data we use the convenient DataSet.Merge() operation to copy DataRows from one DataSet to another.

Answer 1

The best merging algorithm I know is Sort-Merge if your input datasets are sorted by the same attribute. But I do not know C# so well to say if it is possible to force ADO object to use this algorithm.
