In regular day-to-day operation, it will most likely run nicely, with the expectable and documented bandwidth limits ... using it a an Internet exchange router can push the CPU performance a bit if you'd have lots of peering sessions, as well as when building the initial tables ... do keep in mind that not the bandwidth may be a limiting factor, but the number of packets ... being hit with even a small to moderate UDP flood will quickly bring 7200 routers down ...
