        I think you may have hit the nail on the head Pablo. I will have to do 
some
additional testing, but NETBIOS name resolution (nmb) may be the problem. I'll
check when I get back to the office. The host us running Samba 3.2.3-0.1 and
the pertinent part of the config is:

global]
  use sendfile = No
  workgroup = rb_law
  server string = Samba %v
  printcap name = cups
  load printers = yes
  printing = cups
  show add printer wizard = No
  disable spoolss = yes
  log file = /var/log/samba/log.%m
  max log size = 100
  log level = 1
  time server = yes
  smb ports = 139
  hosts allow = 192.168.7. 192.168.6. 127. 66.76.63.120
  map to guest = bad user
  security = user
  encrypt passwords = yes
  smb passwd file = /etc/samba/smbpasswd
   socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
  os level = 57
  name resolve order = wins lmhosts bcast
  wins server = 192.168.7.15
   dns proxy = no
[homes]
   comment = Home Directories
   browseable = no
   writable = yes

        My quest share are also defined with 'net use x: //hostname/home' 
Whatever the
cause, there is a huge slowdown somewhere.
