Keep in mind this a virtual instance of DSS on a Xen host.
DSS is seeing the NIC provided by the host as a realtek adapter. The physical NIC on the host it a 1Gbit broadcom adapter and can be seen by other vms as gigabit adapters.
I reinstalled and there was no difference. Further research leads me to believe the only solution is a pv driver for the nic. I tried a couple other nas type appliances with similar issues.
