That's a good point. However, since this is a production server, I cannot reboot it. Although it was rebooted yesterday. I don't think the network is going to be much of an issue because the directories I'm copying between are local to the server on which I'm testing. I'm making a rough guess on the times, because I had the program that transferred the files record the start and stop times into a file. I think that there might be a +/- of 1-2 minutes in the times but we also sat and marked time with a stopwatch as well because we didn't believe that there could be that much discrepency in the times. I just ran the tests again this morning while the system was relatively quiet and there is not a lot going on on that server anyway.
