samba - Mar 2002 - Win2000 - Very Slow opening files from Samba Share

Hello,

I hope you can be of some assistance.

I am using Samba 2.2.0 on SCO Open Server 5.0.5.
I have a number of various clients on the Network eg Win 98 and Win 2000.

My Unix Server is a PIII 1000, dual CPU computer with dual Raid 1 (mirroring
disks)

Samba is working well from the Win 98 Machines.

However, from the Win 2000 machines when I try to open an Excel file from
one of the Shared Samba drives for example it takes about 2 minutes to open.
The same file only takes a couple of seconds to open from the local C drive.

Are there some settings I need to set in the SMB.CONF file to cope with the
mirroring.

I hope someone out there can help.

I saw this happen on a FreeBSD server.  The solution was to add 
TCP_NODELAY to
the socket options in smb.conf.

I don't have any evidence, but I also suspect that this could be caused 
by name resolution.
You may want to verify the setup of your WINS/DNS.

When we upgraded to 2.2.3a, speed increased dramatically with w2k clients
opening files, especially excel with embedded VB macros.  Apologies in
advance to the list for sounding like a Micro$oft help desk employee, but
you should upgrade.  :)

Take a look at your log files and see if you are getting any oplock_break
messages.   As I just explained in another message, I was having a similar
problem with a Win2K client accessing MSOffice files.  My solution was to
set the 'veto oplock files' directive in smb.conf.  This appears to only
be
effecting my Win2K clients accessing my Samba 2.2.3a shares.  Setting this
option did the trick for me.
