Slow Oracle inserts from SSIS

Struggled for a while, with terrible performance when inserting a couple of millions of rows. Took about 4,5 hours using ole-db or ado.net with different drivers from both Oracle and others.

Tried the Attunity driver, and was stunned. 3,5 minutes instead of 4,5 hours.
