samba performance

[Carl Ma]

Hello all,

In our company, We share all the windows applications from the samba server, 
which is HP LC1000, clients are running Win2000 and map the applications 
filesystem as local disk driver. Everything is ok.

Last week, we switched our samba server from HP LC1000 to a PC server running 
RH6.2. Now the performance for browser & copy is ok, however if we start the 
window applications, it may take 60 - 90 seconds. 

The attached file is my samba configuration. Can anyone advise on it?

Thank you in advance!

# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options (perhaps too
# many!) most of which are not shown in this example
#
# Any line which starts with a ; (semi-colon) or a # (hash) 
# is a comment and is ignored. In this example we will use a #
# for commentry and a ; for parts of the config file that you
# may wish to enable
#
# NOTE: Whenever you modify this file you should run the command "testparm"
# to check that you have not many any basic syntactic errors.
