samba - May 2005 - Intermittent long (~20-second) delays getting to files in a share

Hi,
I'm a newbie to the list, so bear with my ignorance.

I have installed 3.0.14a on FC3, and am using it on a network of 5 XP boxes.

The symptoms are as follows:

When I initially start using the server, there is a significant delay (~
20 seconds) to accessing the share (home directory or a regular file
share). After that I can open files with no problems (near-instant
response) for about 2 minutes. Then I get the same problem again: about a
20-second delay before a file is loaded into notepad/Excel/Etc, then
snappy again for 2 minutes.

I'm told that I should be tweaking the Registry on my XP boxes, but I
can't find out how to do that.

The log entries in log.smbd look like this:

[2005/05/24 08:35:12, 9] smbd/trans2.c:send_trans2_replies(556)
  t2_rep: params_sent_thistime = 2, data_sent_thistime = 40, useable_space
= 131010
[2005/05/24 08:35:12, 9] smbd/trans2.c:send_trans2_replies(558)
  t2_rep: params_to_send = 2, data_to_send = 40, paramsize = 2, datasize = 40

  write_socket(24,104)
[2005/05/24 08:35:12, 6] lib/util_sock.c:write_socket(452)
  write_socket(24,104) wrote 104
[2005/05/24 08:35:23, 10]
lib/util_sock.c:read_smb_length_return_keepalive(505)
  got smb length of 41
[2005/05/24 08:35:23, 6] smbd/process.c:process_smb(1090)

[2005/05/24 08:35:23, 3] smbd/process.c:process_smb(1091)
  Transaction 404 of length 45


Notice the 11 second gap between write_socket(452) and
....return_keepalive(505). Don't know how that turns into a 20-second
delay, but it does.

My smb.conf looks like this:

[global]
    workgroup = CALNUT
    netbios name = Server
    socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
    # os level = 255
    hosts allow = 10.1.33. 192.168.106. 127.0.0.
    # log level = 10
    # oplocks = no
    create mask = 774
    directory mask = 774
    interfaces = eth0 lo
    # local master = yes
    # domain master = yes
    # preferred master = yes
    wins support = yes
    name resolve order = wins lmhosts bcast hosts
    security = user
    username map = /etc/samba/usernamemap.txt
    invalid users = bin daemon adm lp sync shutdown halt mail  \
                    news uucp operator games gopher ftp nobody dbus \
                    vcsa nscd rpm haldaemon netdump sshd rpc rpcuser \
                    nfsnobody mailnull smmsp pcap apache squid \
                    webalizer xfs ntp gdm
[CalnutShared]
    comment = Shared Documents, accessible to all
    path = /home/calnut
    veto oplock files = /*.QBW/
    read only = no
    guest ok = no
    valid users = pthomsen +users

[homes]
    browsable = no
    writable = yes


Any ideas?

Thanks,

I turned off the webclient service, and that seems to have alleviated 
the delay problem.

However, I'm seeing this in the logs (it was there before, too):

Any ideas about that? It doesn't seem to affect the access to the files 
on the shares, but it's annoying in the logs, and I wonder if it's 
relating to a problem that I'm  not seeing?

Thanks,
