You're not going to get more throughput than your NIC allows. They show you
the unrestricted potential throughput to make you realize that the firewall
program itself will not slow you down, because it is capable of much more
than the NIC anyway. Oddly enough, firewall performance, although often
questioned, is almost never a factor to worry about. Almost any firewall on
any platform will perform just fine, with the bottleneck being the NIC.
Depends on the size of the network obviously. But firewall performance is a
much overdone concern IMHO.
