What I'm interested in are some numbers for similar hardware,
to find out if my hardware and/or ethernet driver can be improved,
or if the CPU will always be the limiting factor.
I'd also be interested to know if hardware checksumming
support would improve throughput

The CPU load during the iperf test is around
