So inspired by all this, I've updated xcp with the ability to do parallel copies (at the per-file level). The results are fairly good; I'm seeing 30%-60% speed-ups depending on caching.

The Linux "copy problem"

This is great news - looking forward to trying it. Am also very excited about the work Andreas at RedHat did, enabling GCM crypto for SMB3.1.1 mounts, which can more than double performance copying files to server when on encrypted mounts (in conjunction with two cifs.ko client patches that I recently merged into for-next that enable GCM on the client).
