The data flow task is one of the core elements of SSIS. It is where data is extracted from one or more sources, possibly transformed, and then delivered to one or more destinations. As a result, this task has the most flexibility when it comes to tuning for performance. We will focus on five areas of the data flow that can be adjusted to maximize performance: source acquisition, transforming data, destination loading/updating, lookups, and the data flow in general.

To make a workbook the active workbook, give the activate command to Excel itself, and then give the activate object command followed by the workbook object For example, the following statements activate the workbook named Widget Outputxls:

The data flow can work with data only as fast as it can acquire data from its source. If you can only select rows from a source database at a throughput of 10,000 rows per second, SSIS will be limited to processing no more than 10,000 rows per second as well. As shown in figure 1, the easiest way to determine how fast you can acquire data from a source is to hook the source component up to a Row Count transformation or a Copy Col- Figure 1 An OLE DB Source component umn transformation and execute the data flow hooked up to a Row Count task, taking note of the time it takes to extract transformation your source data. I recommend repeating this process six or more times to establish an average baseline. To use the Row Count transformation, you ll have to set up an SSIS variable to use in the transformation s properties. The Copy Column transformation doesn t have this requirement, and can be hooked up to the source component with no configuration needed. Once you have your extract average baseline, you ll know the fastest possible speed at which SSIS can process your data. To ensure that you have the source properties tuned to achieve maximum performance, follow these tips: Make sure you are using current drivers for your connection. If there are multiple drivers available, be sure to test each one for the best performance, and ensure your packages use the optimum driver.
