By "without much effort" you mean not having to change any network
offload settings, right?

I tested again using:
- Xeon X5450 @3GHz (same machine as earlier test), W2k3, single CPU,
ACPI -> iperf = 1.4 Gbps
- Opteron 2220 SE @2.8 GHz, W2k3, single CPU, ACPI -> iperf = 1 Gbps
So it seems that AMD or Intel doesn't matter much, and neither does ACPI
vs standard PC. The only thing that makes HUGE difference is SMP. Is
this a known issue?
