You know, another way to speed up backup is to change the backup blocking factor.
I think the default is 63 and if you are going over the network, it is certainly feasible to make it 126.
If I recall, there is an environment variable that can be set/modified to change the blocking factor.

Just a lame question here, but how many and type of spindles are behind the volume you are dumping? If you only have a handful of drives, could be the culprit.

Likely a slight boost, but I am at the mercy of the network guys. I do what they tell me.

Stupid question, but isn't 10Gbe a lot faster with e.g. 9000 byte MTU?
I thought I saw in the original post, a 1500 byte MTU:
From original post:
e1a: flags=0x5f4e867<UP,BROADCAST, RUNNING,MULTICAST,TCPCKSUM,NOWINS> mtu 1500
if the 1500 byte MTU can be changed to 9000 without interrupting service
(depends on switch and other configuration, most likely), you might see a speed bump.
