- 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 1700 x objects/hr. At this rate, it will take approximately 10 x days to migrate the entire repository,
- Datastream index: takes about 67 x minutes to build.
- CPU time. Consumes about 15%x%.
- Source layout. Akubra hash storage, using the pattern "#/##/##" for both datastreams and objects.
- 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.
