Speaking of AIX on samba... (and just joined the list myself)
(Some names and dates have been changed to protect the innocent)
Samba server name: HEATHER
Samba server is an IBM RS/6000 F50 with 1.2 GB of RAM and dual ~333 MHz
ppc processors
Samba 3.0.11
AIX 4.3.3 ML10
gcc -v
Reading specs from
/usr/local/lib/gcc-lib/powerpc-ibm-aix4.3.2.0/3.3.4/specs
Configured with: ../gcc-3.3.4/configure --disable-nls
Thread model: aix
gcc version 3.3.4
# Begin smb.conf
# Global parameters
[global]
netbios name = HEATHER
workgroup = CAPSSGRP
username map = /usr/local/samba/lib/smbusers
wins server = 172.16.1.23
[web_calls]
comment = data transfer share
path = /usr/home/web_calls
read only = No
# End smb.conf
Extracted, compiled, and installed form samba-latest tarball source.
We have an application running on a windows 2000 server that mapps a
drive to HEATHER. This application will periodically poll the mapped
drive for files (*.sql - small text files with an MSSQL query in them),
read them, execute the query to an MSSQL server and then delete the
file. This directory can have anywhere from 0-30,000 files in it at any
given time. Whenever the process on the windows 2000 server is
accessing the samba drive the smbd process servicing it pretty much eats
up the cpu on the samba server. The process on the win2k server goes
through the files on the samba drive very slowly no matter how many
files are in it.
Any ideas/suggestions?

Someone from IBM is happily using this for < 100,000 file directories, so I'm comfortable that it works. Jeremy.

This directory rarely has that many files in it. The point I was trying to get across was that the access was slow no matter how many files are there, due to the high cpu utilization of that particular smbd. If the directory has > 3000 files in it...it even slows down on the AIX side and becomes unmanagable. Good to see that someone at IBM is using it that way tho. Thanks for the advice!... -- Jeff Schoby Unix/Network Admin City of Columbia, Missouri 573.874.6320
