Summary

The Data Flow Task is pretty fast by default, but as the data flow grows more complex and the size of data loads increase, the opportunities for tuning the data flow also increase. The guidelines and methods for tuning the data flow described here address a large percentage of the performance issues you'll run into. However, if you still want to get the last drop of performance out of the Data Flow Task, use the Theory of Constraints as your guide to find and eliminate bottlenecks.
