I'm terribly sorry if we didn't pay enough attention to the problems.
I am one (among others) who feels responsible for the Loader and
I read/write on the list.

Yep, could be. It depends of course on the indexes you created.
And you should keep in mind that the tree structures (primary keys)
need some space, too.
And not to forget: as the indexes are simply stored in data files as
statements upon
TABLEEXTRACT (meaning sth like CREATE INDEX bla on blabla)
they need to be recreated on the target db. That may
consume some time (instead of space).

Yes, the Loader works generally with isolation level 3 to have no
inconsistencies. It is at the moment not adjustable with any 
parameter. But we could discuss this topic...

What a pitty ;-)
