SLOW File Copy

Hello,

We have 2 servers, one is a windows 2000 server (P4 1.4 512 ram) the
other is a windows 2003 server with dual xeon cpu's with 2 gigs of
ram. For some reason when you try to copy a file any size wheter 10k
or 10meg to the 2000 server it copies it in a second, when you try to
copy it to the 2003 server which is a lot more powerful it takes a
while to copy. Both servers are Dell, the win2k is a PowerEdge 1400SC
and the win2k3 is a PowerEdge 2800, with dual intel gigabit adapters.
I ran server performance for 24 hours, cpu utiliz is under 5%, mem
usage is roughly 300megs, page file is small, disk queue is small,
network util is under 2%. What could be causing this or how can I
adjust so that the copy is as fast or faster then the old server.

Thank you in advance,
Igor Pinchevskiy

Try disabling SMB signing.

Slow network performance occurs if you copy files to a domain controller
that is running Windows 2000 or Windows Server 2003

or the below (more than likely the above link will help)

You experience slow file server performance and delays occur when you work
with files that are located on a file server

Thanks Ace, for the advice, I disabled SMB signing a while ago. I
found a similar article on google groups that had suggested making the
network card auto negatiable for speed & duplex instead of hard coding
it, and that made all the difference.

That's good. Do you have the link to share it with others that may have the
same problem?

Thanks!

Hello Igor


I have the same problem. I have a DELL win2k server and a DELL win2003
server.
I found that copy file from Win2K server to WinXP client is very fast but
copy file from win2003 server to winxp client is very slow. For win2000
client, there are no any problem.
Could you share any link or information to me ?

Thanks a lot !

Po
