Hello Dave,
Thank you for your reply.
I added the following parameters to the global section:
wins support = yes
name resolve order = wins lmhosts hosts bcast
local master = yes
preferred master = yes
domain master = yes
os level = 65
and set VPN config and DHCP options to use the samba server as WINS
server, and restarted all clients.
I cannot say that the response time to any operation has been improved.
I checked the logs created by Samba for each client: as an example when
trying to "CTRL-C CTRL-V" a 1KB file from explorer nothing in the log
happens for about 17-18 seconds, and only after that time something is
shown:
[2008/03/25 15:17:56, 2] smbd/open.c:open_file(352)
gian opened file docs/divertimento/frame.html read=Yes write=No
(numopen=3)
[2008/03/25 15:17:57, 2] smbd/close.c:close_normal_file(344)
gian closed file docs/divertimento/frame.html (numopen=2)

[2008/03/25 15:18:17, 2] smbd/close.c:close_normal_file(344)
gian closed file docs/divertimento/frame.html (numopen=2)
As you can see, it took about 18 seconds to start the operation (no
logging info), and then 21 more seconds from the first "open" to the
last "close". This is quite annoying.
Did I set something wrong?
Thank you all for any help.
Sincerely
gian

Other services using the VPN such as SCP, SSH, HTTP, FTP work very
good on the same connection, with no slow issues at all. I tried 2
kinds of VPN connections (OpenVPN and a router-proprietary VPN
gateway-to-client), and both have the same issue, both only with Samba.
I wonder if there is something I'm missing in client or server
configuration that makes Samba talking very slow when connections are
not coming from the LAN. The file transfer process works fine: once
the "saving file" or "copying file" process has begun, it takes the
same amount of time needed by a SCP or a FTP transfer command using
the same VPN connection. I tried to copy a 2MB file from client to
server and the time needed using SCP and using SAMBA (once the copy
process was started) was the same.
I have only got this to work nicely by using a WINS server pushed to
OpenVPN clients.
add something like to your openvpn config:
push "dhcp-option WINS 192.168.0.64"
and setup the samba server to be the wins server, and make sure
everyone on the lan points to it too (dhcp can do this)
then name resolution seems to work better, the client avoids
broadcasts, which don't flow over the VPN, and everthing is much faster.
