I think the main speed limiter is this case is database. Copy job do not
operate with raw volumes but creates a new job and mark it as a copy.

Check job output:

 SD Files Written:       1,365,074
 SD Bytes Written:       333,216,925,325 (333.2 GB)

So copy job need to store information in database about 1,365,074 files.
