I would be very interested to see results from a larger scale factor (where the data can't fit into memory any more, as the previous comment mentions), since that is actually where LucidDB is strongest.
LucidDB has a Pentaho bulk load utility now too:

It's currently a plugin, but it's being integrated into PDI as a standard step for an upcoming release.
