One more thing and then I'll leave it at this:
Disabling the dwc on the slave node does NOT slow down the sync, it's
still ticking along happily at 100MB/sec. Can anyone tell me if HP's
RAID6 controller trial licenses have some sort of bandwidth limit
imposed on them? It's hard to imagine, but I've seen worse in my
days. ;-)
Today we installed permanent RAID6 licenses on both boxes, that's why
I'm suspecting the above might actually be the case.
