[ovirt-users] Slow storage migration towards nfs

Heho,
I currently move some vms from fcal-store to nfs, so i can restructure
the fcal storage.

However, i noticed, that dd is running with oflag=direct. I/o is
currently very slow (~160mbit) on the nfs-servers network. Starting dd
without oflag=direct leads to link-speed transmission (~1gbit/s).

So... is this intended beheaviour?

With best Regards,
Tobias
