There's been some discussion on the list regarding software routers
The performance of "software routers" has always had a hardware component.
Basically, for the vast majority of them, take your PCI bus bandwidth, count how many times a packet has to cross it, and do the math. You can't forward more than that much traffic no matter *what* software you run on that box. If that number falls short, stop right there and look for some box of different design that has the required backplane bandwidth.
