Is it?
Last time I check, transfer between domU <-> dom0 (which is all on
virtual interfaces, involving vif and bridge) on a somewhat old
machine (an old Xeon 3.2 GHz) got me around 1-2 Gbps with 100% CPU
usage. So when you have -- say -- a 10Gbps NIC, the physical NIC is no
longer the limiting factor.
