Chapter 22. Troubleshooting SSIS Performance Issues

Performance Profiling

When working with SSIS, there are different performance-related questions that you might have to deal with, such as the following:

SSIS package that is taking longer than usual to complete execution Usually, the normal execution time for an SSIS package that is performing the loading of a fact table is approximately one hour. The SSIS package, which has been scheduled for nightly execution, has been running well for the past six months. ...
