Your test looks pretty reasonable. However, I think a more interesting test would have been to use three machines:

Machine 1: An over-powered PPPoE server connected by 100Mb/s Ethernet to... Machine 2: Running a PPPoE client only, and acting as a router, connected by

           100Mb/s Ethernet to...
Machine 3: Running nc

That way, the PPPoE client is not on the same machine as "nc", so you get a clearer picture of the CPU consumption of the PPPoE software. Also, using 100Mb/s cards gives more possibility to saturate the poor old P90.

Modern machines (not the P90 you used, but let's say a P-III/1GHz) can saturate a 100Mb/s PPPoE link with a few percentage of CPU utilization, in kernel-mode.

Do you need help?
