You on 100Mbit or gigabit? Looks like you're using the default iperf tcp 
windows size which is pretty low (56K I think), try adding a -w 256K or 356K on 
both client/server. You should get much better performance.

For iperf, I had to setup some batch files ahead of time that I could click on 
in My Computer. For a tcp test, 'iperf-1.7.0 -c dom0-name -t 60 -r':

domu->dom0: 31 Mb/s (no loss)
dom0->domu: 36 Mb/s
