samba - Nov 2009 - delay on directory browse

I have a samba file server V.3.3.2 installed on a Ubuntu 9.04 server used
from about 10 workstations in LAN with Windows/MacOSX.
Both OS sometimes when browse some folder have 20-30 seconds delay before
the directory listing.

Here my smb.conf:
[global]

   workgroup = yadayada
   server string = %h server (Samba, Ubuntu)
   log file = /var/log/samba/log.%m
   max log size = 100000
   syslog = 0
   security = share
   load printers = no
   socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
   use sendfile = No
   read raw = yes
   write raw = yes
   #wins support = Yes
   debug level = 3

[Archivio]

        comment = Archivio
        writeable = yes
        path = /home/archivio
        public = yes
        guest account = nobody
        guest ok = yes



And here is some log lines grabbed with verbosity = 3:

[2009/11/13 16:34:35,  3] smbd/oplock_linux.c:linux_init_kernel_oplocks(241)

Any hint? Thanks

This will probably not solve your problem, by why on earth
are you deliberately crippling your performance so badly by
setting the SO_RCVBUF and SO_SNDBUF?
