Just as another source of info here, I'm running:
Dual Core Intel Xeon 3060 @ 2.4Ghz
2 Gb Ram (it says "Mem: 2059280k total, 1258500k used, 800780k
free, 278004k buffers" right now)
2 of these on the motherboard: Ethernet controller: Intel Corporation
82571EB Gigabit Ethernet Controller (rev 06) (port-channel bonded to my
switch)
One other card with 2 ports: Ethernet controller: Intel Corporation
82573E Gigabit Ethernet Controller (Copper) (rev 03)
Gentoo Linux with a fairly small kernel with FIB_TRIE enabled.
I'm taking in 2 full BGP feeds, a decent amount of iptables rules, and
I've hit 1.2 Gbps with no problems. At this point, I just don't have
anything behind the router to push more than that.
