Hi,
I would like to build new router with 3 Gigabit Ethernet card. Need I
dual procesor system or not ? I would like to have trafic controling (htb
or cbq/sfq) and firewall (iptables) on this router.
Can you recommend me some good motherborad with 64-bit PCI-X ?

Having multiple processors may in fact help in this case. Some exciting work is being done in Linux 2.5 development (''NAPI'') which may also interest you.

More to the point, where can you get a motherboard with 3 64x66 PCI buses?(!!) Note that one gigabit card actually can use 2gigabits of PCI bandwidth (one in, one out), and a pci bus is nowhere near 100% efficient, so one 64x66 PCI bus has enough bandwidth to handle 1 such card at full bandwidth, not enough for 2.
Good point . Such was the problem in the first series of Cisco 7000 units. The company was only able to make them do 21.5MB Having said that there are still very few people who would be able to use this. In-house we have built several of these units using both 3Com and Intel cards. I find that two main factors were the most common reason for some sort of failure.. Heat from the cards and Intel cards were just problems. With the 3Com cards we never seems to have a problem. Also - a 100MB control connection was maintained over a third 3Com card.> More to the point, where can you get a motherboard with 3 64x66 PCI > buses?(!!)

What motherboard hardware did you use? Admissions Office wrote:>Good point .
