SMB Server and slow transfer speeds... - Page 4

stw1530 · 04-18-2005, 11:33 AM

Thanks for the response, Hayne! I went ahead and tried entering smb://<fileserver IP address> in the connect to server dialog, and have gotten significantly better speeds for rendering and scrolling through the directories, but there is some strangeness like little boxes with exes in them replacing some characters. Is there anything I should be aware of connecting that way? I'm going to start down the ugly road of finding all the settings in the big picture over here. (it's a bit like the blind leading the blind in my department)

It sounds like there are some characters in the filenames that are not supported by SMB.
You should be aware that SMB does not support all of the metadata that indicates what application is associated with a file. This is likely to cause problems if the files don't have suffixes that indicate their type.

for that info! I'll let my designers know to alwyas include the suffixes. That could have gotten ugly.

Hello.
Taking this thread further.

I have the same problem and the same setting as mentioned.
I have a Mandrake 10.1 server with a Linux 2.6.11 custom kernel, samba 3.0.7.
Currently I'm on a Powerbook with wireless and connecting to Mandrake with samba shares. I'm in need of samba because I also have Windows based computers.

Uploading small files to the server takes seconds, large files takes minutes.
Downloading small files from the server takes seconds, large files takes ages.

I've trimmed my smb.conf settings to this :

Code:

[global]
   workgroup = TAJNETT
   netbios name = tajserver
   server string = local storage provider
   log file = /var/log/samba/log.%m
   max log size = 50
   log level = 1
   hosts allow = 192.168.1. 192.168.2. 127.
   map to guest = bad user
   security = user
   encrypt passwords = yes
   smb passwd file = /etc/samba/smbpasswd
   unix password sync = Yes
   passwd program = /usr/bin/passwd '%u'
   username map = /etc/samba/smbusers
   socket options = IPTOS_LOWDELAY TCP_NODELAY
   read raw = yes
   write raw = yes
   oplocks = yes
   max xmit = 65534
   dead time = 15
   getwd cache = yes
   lpq cache = 30
   dns proxy = no
   default case = lower
   case sensitive = no
   unix charset = ISO8859-15

[homes]
   comment = Home Directories
   browseable = no
   writable = yes
   path = /home/%u

[public]
   comment = Public Stuff
   path = /home/public
   public = yes
   writable = no
   write list = xxxxxx

[shared]
   comment = delt mappe
   path = /home/shared
   valid users = xxx yyyy
   public = no
   writable = yes
   printable = no
   create mask = 0765

I've tried to trim my config file. But It's not optimal yet. Some good advices had been great :-D

I agree with Hayne that the entire concept needs a global approach. I am frustrated with the networking of Macs and Windows Server 2003. Before, when running W2K server, I had no problem downloading and uploading files between Macs and the server. But since the upgrade to Server 2003, the Macs download files at a snails pace.

I've modified the HOSTS file, setup DNS correctly in Network Pane, created a script that resolves unicast DNS for Macs residing on a Windows ".local" domain...MS UAM, Correct File Sharing procedures, etc...
This is a networking issue, probably concerning how W2K3 Server sets security which affects Macs somehow...

I would like to see more information on what's necessary to enable/disable as a security feature regarding AFP or SMB on the server itself so that Macs can get better performance.

any thoughts?

We dealt with this issue for a long time, and i fiddled with setting even sifted through tcp dump logs for mss setting re-negoiation. I believe the first thing we did was turn up the max xmit. Perhaps when we tested last there were other problems with the os x client however we just re-visited this today and lowered the max xmit to 16644 and bang finder operations are lightning fast now.

[global]
log level = 1
log file = /var/log/samba/log.%m

write raw = yes
oplocks = yes
dead time = 15
getwd cache = yes
os level = 255
domain master = yes
preferred master = yes
local master = yes

I've struggling with OSX and SBS 2003 for weeks.

I'm new to OSX, is the global config above on the OSX client side? If so, which directory is this at?

Thanks.

optical · 06-11-2007, 07:18 PM

ok, I found where the config should go but didn't help. Still as slow as hell.

I've put max xmit = 16664 statement on the smb.conf file, rebooted but no effect.

Any other suggestions? This is killing me.
