You need to work out where your bottleneck is. Try this.....
1) Run your extract query in another querying tool. How quickly does it return all data?
2) Remove the insert functionality and remove any data processing functionality (or deactivate it), then run the data query part of the job. What rate do you get?
3) Switch the data processing functionality on, but NOT the insert part. Run it. What rate do you get?
4) Compare the two rates above with the rate you have given us here. That should indicate where your bottleneck is.
Once you have your bottleneck, give us as much info about that section as possible (screenshots, configs, etc).
