Quoth Craig Metz on Mon, 29 March: : : If you're using FreeBSD as a firewall between servers and the Internet, what : really matters here is not the 100Mb/s local links but the speed of your WAN : link, because that's how much traffic is really going to move through that box. : Can FreeBSD keep up with a T1/E1 line? 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.
