 Here are the results from all the possible test combinations between 
 3VMs that are located on two different physical nodes:

 VM1: 10.0.0.5 (node01)
 	—>localhost 		16547.99	10^6bits/sec
 	—>10.0.0.6		2290.46		10^6bits/sec
 	—>10.0.0.7		715.94 		10^6bits/sec

 VM2: 10.0.0.6 (node01)
 	—>localhost		16484.97	10^6bits/sec
 	—>10.0.0.5		2346.11		10^6bits/sec
 	—>10.0.0.7		715.15		10^6bits/sec

 VM3: 10.0.0.7 (node02)
 	—>localhost		22090.21	10^6bits/sec
 	—>10.0.0.5		483.38		10^6bits/sec
 	—>10.0.0.6		584.02		10^6bits/sec


 Thanks for your time!
