Hi Thomas,

>@Markus: Do you think such an approach would be considered cheating ?

1. It's allowed to create Table1 at runtime.
2. After step 1 the contents of Adressen.txt have to be in Table1.

IMHO we can cheat as we like as long as we get there. But I wouldn't go that far. Removing duplicates faster will gain more overall speed.
