rsh <ip-src> netperf -H <ip-tgt> -- -S 256000 -s 256000

Where ip-src and ip-tgt were all separate machines (20 machines total)
none of which were the head node.

I saw wire speed on them all (> 900 Mbit/second), usually close to
940 Mbit/second.  So perhaps 10 GB/s switch (minimum), at least in this
configuration.

This was only a 10 second test...   Your milage may vary...
