Yeah, that's what i meant to say. DRBD provides a handful other tweaks
besides changing the sync protocol, i'd start with them first. You can get
back experimenting with the sync protocol if there are still performance
issues then. I don't hesitate changing to B as long as I'm aware that it
changed semantics and I can deal with them.
