28. 01. 2010 Test of data transfer latency at PSI

Method : subscribe one by one the following datasets:

/MinimumBias/BeamCommissioning09-BSCNOBEAMHALO-Dec19thSkim_341_v2/RAW-RECO
/MinimumBias/BeamCommissioning09-RecoTracks-Dec19thSkim_341_v2/RAW-RECO
/MinimumBias/BeamCommissioning09-SD_InterestingEvents-Dec19thSkim_341_v1/RAW-RECO
/MinimumBias/BeamCommissioning09-SD_InterestingEvents_MinBias10-Dec19thSkim_341_v1/RAW-RECO
/MinimumBias/BeamCommissioning09-SD_AllMinBias-Dec19thSkim_341_v1/RAW-RECO

and keep track of the latecy in the transfer begin, transfer speed and sources

TOTAL

(1) The transfer would have been completed around that time, but the last two files started failing at FNAL (timeout. Debug transfers from RWTH are ok, so a proxy issue excluded). Transfer actually ended ~31/1/2010, with the transfer of the last two files from RWTH

(2) Subscribed both at CSCS and PSI
