Copy from NAS Drive to /from 2 or More Win 7 x64 isvery s-l-o-w
Posted on 2011-04-22
We have 3 machines running win7 x64with min of 4 G ram and all have 1G nIC and we hae 1 G switch. We also have a NAS Drive with a 1G NIC. When one machine copies a large directory of files or just a single large file from or to the NAS drive, copying takes place at expected nettwork speed = e.g. one set is about 3 mins. - approx same speed if copying to /from the NAS Drive using a Win XP Pro computer. When we try copying from / to NAS drive on 2 Win 7 computers concurrently, what took 3 mins now takes 3/4 hr. I disabled all TCP Task-Offload options to no avail. What else can we do? Copying these large sess using the 2 Win XP Pro computers concurrently takes far less time. Suggestions?
