I like multicore / multicpu amd opteron boards from Tyan. With a dual
core (later you can double to 4 core) dual cpu motherboard, you can
route and shape to your hearts content. To really improve throughput,
you should use a higher end network controller with pci-express with
some smarts and

I have a router with a large number of iptables rules and some extensive
traffic shaping (HTB + RED + ... ) + conntrack.
The router is running Centos5 on a P4 Celeron 2.4 with 512Mb ram
30% soft interrupt cpu utilisation
7000 packets/second on each of eth1 and eth0 (forwarded packets)

Performance boost tips:
- Use set module instead of sequential iptables rules. It can lower
cpu usage.
Hmm - I don't

Search for ipset extensions for iptables or look up extension projects
in netfilter.org.
ipset gives the facility to create sets of IPs and use the sets in

1. What processors should I be looking for in order to achieve the
best routing throughput on a linux router?
I've had good experiences with P4 (with and without HT), Athlon64, Xeon
[dempsey], Xeon [woodcrest]. The last one is the best choice
