The confirmation test (IG-CT-1 - Access to New Site VM resources) has consistently found poor TCP performance results for all initial racks (GPO, Northwestern, Utah). For IG-CT-1, measurements were captures from VM to VM within one rack over TCP for a duration of 60 seconds for 1, 5 and 10 iperf client connections. In all cases VMs assigned were on the same node. ||'''End points'''||'''One Client'''||'''5 Clients''' ||'''10 Clients'''||'''Ping rtt min/avg/max/mdev'''|| || GPO ||294 Kbits/sec || 1.68 Mbits/sec || 3.45 Mbits/sec ||0.025/0.030/0.042/0.006 ms || || Northwestern ||294 Kbits/sec || 1.65 Mbits/sec || 3.52 Mbits/sec ||0.025/0.029/0.048/0.007 ms || || Utah ||294 Kbits/sec || 1.52 Mbits/sec || 3.48 Mbits/sec ||0.019/0.029/0.045/0.006 ms || The results as captured for the test runs at each rack: - http://groups.geni.net/geni/wiki/GENIRacksHome/InstageniRacks/ConfirmationTestStatus/GPO#Measurements - http://groups.geni.net/geni/wiki/GENIRacksHome/InstageniRacks/ConfirmationTestStatus/Northwestern#Measurements - http://groups.geni.net/geni/wiki/GENIRacksHome/InstageniRacks/ConfirmationTestStatus/Utah#Measurements" closed major Experiment SPIRAL5 fixed confirmation tests
