Firstly I need to reproduce the problem. I haven't been able to do

I can start to experiment with fixing the problem.
*Exactly* what are you doing to see this problem/SMB traffic pattern from
an XP client ?
All I am doing is running the evaluation version of PerformanceTest V5.0
that I downloaded from http://www.passmark.com/. I go to Edit /
Preferences on the windows app, select my network mapped disk drive,
leave the test duration as 3 secs and number of processes as 1, and then
go to Tests / Disk and select the "All" option to test sequential read,
write and random seek + RW.
When I do this it takes a lot longer than 3 seconds, and my smbd process
on the server hovers around 10% cpu usage for several seconds, then
heads up to 95-99% and stays there for what appears to be the duration
of the write test. During this time there is no other activities going
on on the machine. The Sequential Write portion of the test lasts a
very long time - around 30 or 40 minutes.
The reason why I'm doing this test is that I've observed that working
with this networked drive from a winxp client "seems slow", so I'm
trying to benchmark the performance so I can identify where the problem
is and determine if any "fixes" I do have made anything better.
I'm using an out-of-the-box FC3 system (2.6.9-1.667), and samba
3.0.14a-1. Samba config file I sent in on the initial post.
I do not notice any slowness over nfs. However, that was why I was
wondering if there are some linux benchmarking tools that I should try
using to get more information on this problem.
Thanks,
Don
