Ok, that's what I wanted to know. In this case Samba in theory has a
chance. Not that we would jump on this immediately and get a solution next
month, but this is a workload that many people have pressure to improve.

Unfortunately opening a file for SMB is a pretty complex task, so making
that fully parallel without too much context switch overhead is difficult.

I'd have loved to blame this on the client, but not this time :-)
