Understand your source system and how fast you extract from it. After all, Integration Services cannot be tuned beyond the speed of your source – i.e., you cannot transform data faster than you can read it. Measure the speed of the source system by creating a very simple package reading data from your source with the a destination of “Row Count”:

Execute the package from the command line (DTEXEC) and measure the time it took for it to complete its task. Use the Integration Services log output to get an accurate calculation of the time. You want to calculate rows per second:

Based on this value, you now know the maximum number of rows per second you can read from the source – this is also the roof on how fast you can transform your data. To increase this Rows / sec calculation, you can do the following:

• Improve drivers and driver configurations: Make sure you are using the most up-to-date driver configurations for your network, data source, and disk I/O. Often the default network drivers on your server are not configured optimally for the network stack, which results in performance degradations when there are a high number of throughput requests. Note that for 64-bit systems, at design time you may be loading 32-bit drivers; ensure that at run time you are using 64-bit drivers.
• Start multiple connections: To overcome limitations of drivers, you can try to start multiple connections to your data source. As long as the source can handle many concurrent connections, you may see an increase in throughput if you start several extracts at once. If concurrency is causing locking or blocking issues, consider partitioning the source and having your packages read from different partitions to more evenly distribute the load.
• Use multiple NIC cards: If the network is your bottleneck and you’ve already ensured that you’re using gigabit network cards and routers, then a potential solution is to use multiple NIC cards per server. Note that you will have to be careful when you configure multiple NIC environments; otherwise you will have network conflicts.
