samba - Aug 2007 - FW: Slow opening files on Samba Version 3.0.22 (UPDATED)

Hello,
 
  We are running Samba Version 3.0.22-13.30-1290-SUSE-SLES10  on an iSeries
LPAR with 512 memory and .10 of the processor and a GB NIC.  I have
successfully joined this server to our Windows 2000 active directory.   I
have copied over some data and setup some test shares and mapped the share
on my pc.    I can browse the files in the share with no problem but when I
open any type of file on this server it takes 5-10 seconds to open a file.
The files I am opening are really small files (around 16k).  Closing the
file take a little longer than expected. 
 
I noticed that when I opened the file on the server the smbd process takes
80% of the CPU until the file is opened.
 
Does anyone have any ideas?
 
Thanks in advance!

What is smbd doing at this point? "strace -p <pid>" might
shed some light on that.

Other people (me included) have seen that. Now that I've moved us to 
3.0.24 (Ubuntu 7.04 Feisty Server), I'm not seeing that kind of 
behavior. I can't be completely sure if it was the upgrade or some 
changes to my smb.conf required by the upgrade that did it. Do you have 
a test environment to try out your configuration on 3.0.24 or higher?
