[Samba] once again: horrible speed!

[Joel Hammer]

Knowing nothing about this, I would ask:
1. What is the association between size of file and tranfer time? Linear,
step function, curivlinear, etc? It might be informative to transfer
different file sizes and plot the transfer times against the file
size. This might suggest resource depletion (memory, cpu cycles) if it were a step
function, for example.

2. Are all file types affected?

3. You are sure the w2k client is not wasting time on the upload, perhaps
doing some extra security checking? A tcpdump on the server during a
w2k upload might be interesting. Compare it to a dump while transferring
files from the win_me client. sort, uniq, and diff might help to sniff
through the tcpdump files.  Just a difference in the size of the files
would be interesting. For example, is there a lot more traffic when w2k
is uploading then when win_me is uploading or when samba is downloading
to w2k?

4. Do you have all the latest patches for w2k?

I would run top during the transfer to see what is happening to your
server's resources during transfer.  You can run top with options for update
intervals and can save the output to a file.
