Significant performance difference in executing a transformation locally or via Carte

Hi,

I have seen the following behaviour: I have got a transformation which is performing an Insert/Update at the end and is part of a job. When I am executing the job locally or via Carte, the Insert/Update step achives roundabout 23 r/s (target database is Postgres). But when I am executing the transformation directly on the Carte server, the step has a performance of about 400 r/s.

Is there a specific reason for this performance difference?
Regards
