Hi Adam,
Actually we are really having 4M/4M, because other traffic gets very
well. I tried with download file via HTTP and it did gave us such a
result. (Or I download files from that network, the performance is
also satisfying.)
I think the main problem is the way that Excel file being opened,
not Samba. If this is a Samba problem, I'm sure that I will encouter
this problem in my local LAN too! But if anyone knows the ways to
improve the situation, I will be glad to hear. =)
Currently everyone agree the problem is latency, as another user in
the list suggest that we should have temp. file on local, not on the
share, but I cannot figure out the way to do that!
Thanks for your help!
Yours sincerely,
Jason Chan

When I tried to do a throughput monitor, hey, it seems only used up
some hundred Kbit/second of the bandwidth, however we have around
4Mbps for the internet access in both sides (Hong Kong and China).
However I do agree that the latency causes so much problem.
If you have Internet connections on both ends and are using a VPN then
you are probably screwed. If your 4Mbps is a point-to-point link there
is more you can do. But you still might be able to gain something by
adjusting the MRU/MTU/Window/etc... of your VPN connection. But the
latency on Internet links is usually pretty bad.
And is your connection really 4Mbps both up and down stream?
Anyway, I don't think this is a Samba issue but a basic networking
issue.
