I think Shilen said his went a lot quicker on Oracle (~1 hour?), but somehow
Duke's oracle is very quick (when he and I run the same data generation
script, his oracle runs faster then mine). Anyways, to answer your
question... the generated DDL script can have indexes moved around wherever
you want. It might help a lot for the data massaging. It will spit out the
code to do incremental changes, but it might not be the most efficient thing.
If there are easy solutions with temporary indexes (e.g. on memberships
table), let me know and we could perhaps add to the generated DDL, or at
least let people know so they can save some time by manually changing it.

Btw, regarding the db drivers thing, I believe they should go into lib/custom
(if that exists in the quick start) not lib/grouper, though I need to work
more with the quick start to be sure. If that is the case, I agree with TomZ
where it would be a quicker start to put all the DB drivers into lib/custom
(they would be the only jars there), and it wouldn't confuse the user as much
as the jars hidden in the lib/grouper dir where all the other jars are...
