- 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.
- Speed: The tool migrates approximately x objects/hr. At this rate, it will take approximately x days to migrate the entire repository,
- Datastream index: takes about 1h10m minutes to build.
- CPU time. Consumes about x% on average.
- Source layout. Akubra hash storage, using the pattern "#/##/##" for both datastreams and objects.
