Pfsense doesn't do well performance wise virtalized. At least it didn't used to. I think they have a pay for version optimized for VM platforms.
It's just FreeBSD plus drivers, right? It should do as well as FreeBSD does on whatever platform is in question. That FreeBSD doesn't have PV support for Xen is a major drawback to FreeBSD as a platform in general. But it should only be a question of drivers, in general.
