So you're convinced the speed bottleneck is firmly on the filesystem/disk array?
I've noticed that changing the SSH cipher helps substantially sometimes; but
sometimes (often?) not much. It's a worthwhile optimization when it works
tho. I think I've seen 10-15% improvement in backup times.
As for your link issues; the suggestion that it may be a keepalive problem
reminded me of this tool:

It may be worth trying that.
