I'd be surprised if it couldn't. Can : FreeBSD keep up with a DS3? Given good enough hardware, probably. Faster than : that as total traffic going through the box and you need to worry. Since the discussion is occurring at this level, it is probably helpful to note that the *size* of the packets also plays a large role in determining maximum routing throughput: The box has to do a lot more routing for 512B packets than it does for 1024B packets at the same bandwidth. I'm guessing that a thorough search would show up some clock vs. packet-size vs. bandwidth limit graphs for FreeBSD, Linux, various commerical routers.
