Excessive CPU usage for network traffic

Hi,
When I push 100mbps through my Z77 board's RTL8168 NIC, all VMs in the
network hierarchy above the originating VM spike to ~25% CPU usage.
Looking inside sys-net and sys-firewall, I see most of the time is spent
in [vif*-q1-gues]. I don't know what it is, other than apparently some
process to handle virtual interface packet processing.
Perhaps this problem is not Qubes-specific, but is there any way to
reduce this load? It seems a bit excessive.
