[Samba] Please Help --- Samba accessing share very slowly

[mallapadi niranjan]

Hi all

I have a samba 3.0.21c with openldap 2.3.19,  with another linux system
having samba 3.0.21c acting as domain member server. (file server)
all my client access the file server shares extensively. about 100 users
access the file server at time,
this is making things very slow, on the file server about 180 smbd process
are getting created. on the file server i have 1gb of RAM with
2Gb of swap space, it occupies all the 1gb but never access swap space. The
share that they access is of 40gb of data
The access to the file server becomes so slow that all my client systems get
hanged (clients system windows 2k professional)
The server architecture of my file server IBM 226 series xeon server with
1gb ram and 73Gb hard disk.

on the file server when we do
smbclient //filesrv/share -U root%redhat
it says server did not respond after 20000 milliseconds.
what could be the problem is it that i need to upgrage the RAM, or
plese suggest  or
can we do any changes share defination of smb.conf of my file server so that
access becomes quick.
the following is my smb.conf of domain member server ( file server)
