Just an update on the above...

I updated to the latest 2.0-BETA2 version of pfsense and that has seemed 
to have solved my link rate issue. Using e1000 for the LAN interface, 
and PCI passthrough for the WAN, the system caps out at around 110Mbp/s, 
which is good (and acceptable for me, as my colo's internet connection 
will be 100Mbp/s).
One thing I did note however, was that it only worked this well when 
there was only 1 vcpu in the guest....
Can anybody explain this behaviour?
