We have what I think is somewhat of a "strange" problem.
We have a share being hosted off of our Samba server. The Samba server is
an RS/6000 H-80, 1Gb of Ram, dual RISC processors, FCAL connected RAID disk,
running AIX 4.3.3 untuned, out of the box. Samba is version 2.2.0 from the
distribution set on the Samba.org website.
When I do an NT map to the drive share, and then browse it with windows
explorer, it takes around 20 to 30 seconds to show the information in the
windows explorer window. Further, while my machine is building this
explorer window, if I were to go to a DOS prompt and do a DIR from a
different machine, the share itself would appear to be "locked" until
the
explorer window updates.
Share structure is as below
\SERVERNAME\CIMS
\XXX
\YYYY
\2001-06-14
This directory has over 13,000 files, with the smallest being 43K and the
largest being 4M. The average is around 150Kb.
I have included the smb.conf file (global section, and the section
responsible for the share). Any thoughts on as to why we experience this
slowdown would be appreciated.

The average is around 150Kb.That's why. Remember that smbd has to generate 8.3 filenames and perform case insensitive matching. Any chance of reorganizing your directory structure? cheers, jerry --------------------------------------------------------------------- www.samba.org SAMBA Team jerry_at_samba.org www.plainjoe.org jerry_at_plainjoe.org --"I never saved anything for the swim back."

Yes it is possible to reorg some of the directories, particularily the converted plans. COMS would also have to be rewritten to space out file locations. Can the 8.3 notation be turned off ? We do not need backward compatibility. Can case insensitivity be turned off ? Almost all of our file names are numbers eg. 12123_12133.

Our current settings are: case sensitive = no preserve case = Yes short preserve case = Yes Is this not the most optimized method already? Our current clients are NT/2000 only...
