Alan, I find that a little surprising, considering that I use a 486-66 for my home firewall. I've never really noticed any network slowdown because of it, and it's considerably slower than any S/390 system that can run Linux/390. Do you have some references for this that I could read to increase my understanding? I've been suggesting putting firewalls on Linux/390, and I don't want to continue doing that if it's the wrong thing to do.
The latency critical part I understand, but if you're on a zSeries machine, HiperSockets should avoid that problem, I would think.

Obviously this makes more sense I would be very suprised if it was. A firewall tends to be very cpu and latency critical rather than about bulk I/O throughput. Maybe it works but I'd like to see the evidence. -snip-
