We are in the process of virtualizing many of the servers we use at the office and have encountered and issue that I didn’t expect and cannot see a reason for. When backing up, or copying large files (over 1GB) the process goes so slow that it practically cannot be done. For example, I copied a couple of smaller files – about 2MB each – in a minute or so each. However, when I tried to copy a 3GB file it took several hours and then was only partially done. The impact on the network is that a backup that should take a few hours has exploded to over 60 hours.
Has anyone else experenced this? If so, what is the best way to fix it?
