I created and prepositioned approximately a 725Mb share. The preposition status reports that the directive took 15 minutes to complete. We then connected to a PC at the remote location and mapped to the share here at corporate. We then copied the files from this share to the desktop and it took about 2 minutes. We then copied these same files from a second non-prepositioned share and the transfer time was about 2-3 minutes. I would have expected the second copy from the non-prepositioned share to be longer. I am taking these results to be that the DRE and CIFS cache are both populated because of the prepositioning. Is this a valid test to compare prepositioning -vs- non-prepositioning? Tonight I am going to update the prepositioing and see what it's reduced time will be with modified copies of the original files. We will then see what the copy results will be tomorrow.
We are trying to establish a base line and extrapolate times and things before we attempt an 80Gb prepositioning. Is there a different approach we should be taking for this test? Do these results seem about normal?
