Yes, it is a hard question to answer, that I am aware of.

The drivers are those which come with a SQL 2008 R2 installation, so I would guess not the latest drivers.

I believe the pipe & components between are good. I don't have much info on the DB2 machine itself, but other source systems to this particular server function at much higher rates of through put.

I will have to find out on the throttling at the source, that is one of the things I was wondering about myself.

It is using the fast load settings.

Packet size is set to: I am sure it is set to the default.

Would anyone know if there is a high speed DB2 driver anywhere? I know for example, that for an Oracle system Attunity is a good high speed driver which has helped transfer speed for me in the past.

Maybe a simpler question would be what is a reasonable through put for a data pull from DB2? I have no experience with DB2 elsewhere, my expectations might be too high.
