Until this functionality is added to the crowd-integration-client JAR permanently, you can TEMPORARILY replace the crowd-integration-client JAR file in either JIRA or Confluence's WEB-INF/lib directory with one of the attached. Use the 1.4.1 JAR if using Crowd 1.4.x. Use the 1.3.2 JAR if using Crowd 1.3.x.
Once the JAR is in place, restart the client application (e.g. JIRA or Confluence) and enable profiling in the client application (Admin -> Logging & Profiling). The resulting logs should contain additional profiling information about Crowd performance.
Once testing is complete, restore the original crowd-integration-client JAR file and restart your client app.
