Library name and version

Azure.Storage.DataMovement.Blobs 12.0.0

Query/Question

Trying to use Azure.Storage.DataMovement to copy whole containers either within or across storage accounts from a console app. It works, but is a lot slower than using AzCopy. Should/could it be comparable in speed?

Test example with 7.5GB container containing 80k files

• AzCopy (default options) took 4 minutes
• TransferManager.StartTransferAsync took 30 minutes

Changing MaximumConcurrency to 64 (value we used for ParallelOperations with the old library) had no impact (its a nullable int so not sure what the default is).

Previously, for the old library, we also set System.Net.ServicePointManager.DefaultConnectionLimit = Environment.ProcessorCount * 8 - which also had no impact to the library
