      All included branches are being scanned for a Jenkinsfile for each included pattern.  In production, the same branch is being scanned 32 times, resulting in an execution time of 30 seconds for the multibranch scan, rather than 1 second.  We have 16 included patterns.

      Project repository base: svn://repo/repo1
      Include branches: branches/TeamA-, branches/BUG-

      Example output (a test repo with only a couple of branches):
