 Two node iperf test:
 Ran iperf between two nodes for the latest kernel 2.6.21. The throughput
 is 1.9 Mbps(15 minute test). This test was run in a shielded room. The
 moment I open the door of the shielded room the throughput drops to 0 but
 recovers when the door is closed.

 Three node iperf test:

 Ran iperf between two nodes (with a third intermediate node in between)
 for the latest kernel 2.6.21. The throughput is 2.9 Mbps (15 minute test).
 There is quite a bit of fluctuation in the throughput over the 15 min
 period (from 1.4 Mbps - 2.9 Mbps). This test was run in a shielded room.
 Once again the moment door of the shielded room is opened the throughput
 drops low.
