Identifying Target Bottlenecks

Identifying Target Bottlenecks

To identify a target bottleneck, complete the following tasks:
  • Configure a copy of the session to write to a flat file target. If the session performance increases significantly, you have a target bottleneck. If a session already writes to a flat file target, you probably do not have a target bottleneck.
  • Read the thread statistics in the session log. When the Integration Service spends more time on the writer thread than the transformation or reader threads, you have a target bottleneck.
