[LARTC] Which CPU for heavy traffic with much filtering/shaping?

[Marco C. Coelho]

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 multiple ports if you need it.

Hope that helps.
