I've got two XP machines on my home network (linksys wrk54g) that I'm
moving ~14Gb of data between. Now, I don't expect the full 100Mb/s
throughput but it seems to be exceedingly slow. In about 12 hours, I've
moved around 1.9Gb which comes to about .337Mb/s.

Any ideas what the problem might be?

David,

Your question comes up occasionally. Copying files form one computer to another
is a complex procedure, though it may not look that way to you.

Please start with my article on diagnosing network problems.

Now if you have a WiFi network, are the computers connected by Ethernet, or
WiFi? If both are using WiFi, then you have a duplexing problem. This is a
relevant detail, which is needed immediately.

And, of course, whenever WiFi is involved, there will always be limitations.

Besides the physical connectivity possibilities, there are protocol problems,
and possible performance problems on the computers themselves. But as I like to
diagnose problems in a layered sequence, let's concentrate on the physical
network first.

Unbelievable...I just 're-connected' the computers (wirelessly) and
find that I'm now on track to move 12+ Gb of data in < 2hrs! What's it
take to predict throughput?!?!?

So, it's interesting that I was having the problems wired but not
wirelessly. I'll test the wired again after this transfer is complete
and report back the findings.

Geez!

David

New observation: The files I'm moving are music files. I notice that
the time estimate for the transfer increases considerably when I start
WMP. Might this have been related to my problems? Mind you, the files
that were moving slowly were NOT being played but WMP was up and
running.

Thanks again,
David


I've confirmed that the problem is when I'm connected via Ethernet.
Wirelessly, I'm fine.

Any thoughts what it might be then?

Thanks again,
David

David,

Differences between Ethernet and WiFi:
# Network device drivers.
# Network devices.
# Cables.
# Router ports.

When you connect Ethernet, do you do both computers by Ethernet? WiFi?

Do you have current drivers / firmware on network devices? Router?

Inventory network equipment (make / model), and how everything connects.
