I couldn't really understand the meaning of Carlos' benchmarks, since
it looks like he did other changes (like deactivating indexes and
committing every x inserts) other than switching to IBO. In addition,
a meaningful benchmarks should act on the same database each time and
Carlos didn't say whether this one has been conducted this way or not.

Anyway, I am particularly concerned by the poor performance of
IBODataSet, but I'm glad to know IB_SQL is a different matter
altogether and that you solved your problems.
