throughputs:
dom0 <- outside -- 942Mbps
domU <- dom0 -- 3467Mbps
domU <- outside -- 87Mbps
The NIC on the machine is 1GE.
What puzzles me is, some instances of domU (with same config) is able to

configured on znic0. When there is no maxbw, the throughtput is
as expected; when maxbw is 55M the throughput only drops to 76 Mbps:
