Interesting. What did you set the "Inser batch size" to? (I think that's
available for all transformatino tasks). And did you remember to check
the box for "use transactions"?
While it's never as fast as a COPY, it should be possible to make it
faster than that, Ithink.
Another option is to just BCP the file out, and then COPY it into
postgresql. No nice GUI, but you can tune almost everything with BCP.
