SSIS Optimization - Adjust the packet-size

A key network property is the packet size of your connection. By default this value is set to 4,096 bytes. This means a new network package must be assemble for every 4 KB of data. Increasing the packet size will improve performance because fewer network read and write operations are required to transfer a large data set. If your system is transactional in nature, with many small data size read/writes, lowering the value will improve performance.

Since Integration Services is all about moving large amounts of data, you want to minimize the network overhead. This means that the value 32K (32767) is the fastest option. While it is possible to configure the network packet size on a server level using sp_configure, you should not do this. The database administrator may have reasons to use a different server setting than 32K. Instead, override the server settings in the connection manager as illustrated below.

Another network tuning technique is to use network affinity at the operating system level. At high throughputs, you can sometimes improve performance this way.

For the network itself, you may want to work with your network specialists to enable jumbo frames to increase the default payload of 1,500 bytes to 9,000 bytes. By enabling jumbo frames, you will further decrease the amount of network operation required to move large data sets.
