  1. Storage environment:  for the purposes of this test (and for our real migration), we are migrating from one CIFS-mounted remote filesystem to another CIFS-mounted remote filesystem.
  2. Speed: The tool migrates approximately x objects/hr.  At this rate, it will take approximately x days to migrate the entire repository,
  3. Datastream index:  takes about x 1h20m minutes to build.
  4. CPU time. Consumes about x%.
  5. Source layout.  Akubra hash storage, using the pattern "#/##/##" for both datastreams and objects.
  6. OCFL storage:  Pairtree.  It will be good when the OCFL storage profile specification is set and incorporated into migration-utils, so that we can define the OCFL layout, similar to how we can specify the Akubra filesystem layout.
