Eliminating Bottlenecks Based on Thread Statistics

Eliminating Bottlenecks Based on Thread Statistics

Complete the following tasks to eliminate bottlenecks based on thread statistics:
  • If the reader or writer thread is 100% busy, consider using string datatypes in the source or target ports. Non-string ports require more processing.
  • If a transformation thread is 100% busy, consider adding a partition point in the segment. When you add partition points to the mapping, the Integration Service increases the number of transformation threads it uses for the session. However, if the machine is already running at or near full capacity, do not add more threads.
  • If one transformation requires more processing time than the others, consider adding a pass-through partition point to the transformation.
