Hardly worth it, eh?
Well, if you're going to do scp, you're CPU-bound rather than NIC-bound,
since SCP needs to encrypt. What happens if you use something less
taxing on the CPU, like HTTP or some such?
(n)ttcp? netperf?
Yes, ssh overhead on low-performance CPUs is significant. Ask Arno about
his experiences on MicroVAX ;-)
