Nah, thats just what the model of the emulated network-card has as through-
put, you can do more with HVM as you can see from my small benching at
http://fluxcoil.net/doku.php/xen/docs .

Use paravirtualized drivers if you can get those for the OS you are running
under HVM (my benchmark misses the case HVM/paradrivers thou, since para
is the most interesting method and HVM was just a fun here to look at).

Maybe someone has an explanation for the difference throughput
dom0->domU vs. domU->dom0 .
