Slow Samba Transfers Ubuntu 8.10

Postposted on Sat May 09, 2009 12:01 am

So I just put together a little linux media server.

E1400
2x2gb ddr2 800
1TB
Gigabit Ethernet
Ubuntu 8.10 running off a 4GB CF x133 Card

I was able to transfer files to it from my other computer really quickly (like 20-50MiB/s),
but now I have it configured for network sharing and I am getting like 2 MiB/s transfer speeds. Grrrr

Looking at the system monitor during transfers shows that there is ample processing power and hardly any ram usage. I have 200+ MB space free on the OS CF drive.

I am new to Linux and have no idea why this is happening. any suggestions?

Here is my smb.conf file:


#======================= Global Settings =======================

[global]

## Browsing/Identification ###

netbios name = XXXXXX

# Change this to the workgroup/NT-domain name your Samba server will part of
workgroup = XXXXXX

# server string is the equivalent of the NT Description field
server string = XXXXXX

# Windows Internet Name Serving Support Section:
# WINS Support - Tells the NMBD component of Samba to enable its WINS Server
# wins support = no

# WINS Server - Tells the NMBD components of Samba to be a WINS Client
# Note: Samba can be either a WINS Server, or a WINS Client, but NOT both
wins server = XXX.XXX.XX.XXX
###^hope this works?
remote announce = XXX.XXX.XX.XXX/xxxxxx XXX.XXX.XX.XXX/xxxxxxx
###^hope this works?

# This will prevent nmbd to search for NetBIOS names through DNS.
dns proxy = no

# What naming service and in what order should we use to resolve host names
# to IP addresses
; name resolve order = lmhosts host wins bcast

#### Networking ####

# The specific set of interfaces / networks to bind to
# This can be either the interface name or an IP address/netmask;
# interface names are normally preferred
; interfaces = 127.0.0.0/8 eth0

# Only bind to the named interfaces and/or networks; you must use the
# 'interfaces' option above to use this.
# It is recommended that you enable this feature if your Samba machine is
# not protected by a firewall or is a firewall itself. However, this
# option cannot handle dynamic or non-broadcast interfaces correctly.
; bind interfaces only = yes



#### Debugging/Accounting ####

# This tells Samba to use a separate log file for each machine
# that connects
log file = /var/log/samba/log.%m

# Cap the size of the individual log files (in KiB).
max log size = 1000

# If you want Samba to only log through syslog then set the following
# parameter to 'yes'.
# syslog only = no

# We want Samba to log a minimum amount of information to syslog. Everything
# should go to /var/log/samba/log.{smbd,nmbd} instead. If you want to log
# through syslog you should set the following parameter to something higher.
syslog = 0

# Do something sensible when Samba crashes: mail the admin a backtrace
panic action = /usr/share/samba/panic-action %d


####### Authentication #######

# "security = user" is always a good idea. This will require a Unix account
# in this server for every user accessing the server. See
# /usr/share/doc/samba-doc/htmldocs/Samba3-HOWTO/ServerType.html
# in the samba-doc package for details.
# security = user

# You may wish to use password encryption. See the section on
# 'encrypt passwords' in the smb.conf(5) manpage before enabling.
encrypt passwords = true

# If you are using encrypted passwords, Samba will need to know what
# password database type you are using.
passdb backend = tdbsam

obey pam restrictions = yes

# This boolean parameter controls whether Samba attempts to sync the Unix
# password with the SMB password when the encrypted SMB password in the
# passdb is changed.
unix password sync = yes

# For Unix password sync to work on a Debian GNU/Linux system, the following
# parameters must be set (thanks to Ian Kahan <<kahan@informatik.tu-muenchen.de> for
# sending the correct chat script for the passwd program in Debian Sarge).
passwd program = /usr/bin/passwd %u
passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .

# This boolean controls whether PAM will be used for password changes
# when requested by an SMB client instead of the program listed in
# 'passwd program'. The default is 'no'.
pam password change = yes

# This option controls how unsuccessful authentication attempts are mapped
# to anonymous connections
map to guest = bad user

########## Domains ###########

# Is this machine able to authenticate users. Both PDC and BDC
# must have this setting enabled. If you are the BDC you must
# change the 'domain master' setting to no
#
; domain logons = yes
#
# The following setting only takes effect if 'domain logons' is set
# It specifies the location of the user's profile directory
# from the client point of view)
# The following required a [profiles] share to be setup on the
# samba server (see below)
; logon path = \\%N\profiles\%U
# Another common choice is storing the profile in the user's home directory
# (this is Samba's default)
# logon path = \\%N\%U\profile

# The following setting only takes effect if 'domain logons' is set
# It specifies the location of a user's home directory (from the client
# point of view)
; logon drive = H:
# logon home = \\%N\%U

# The following setting only takes effect if 'domain logons' is set
# It specifies the script to run during logon. The script must be stored
# in the [netlogon] share
# NOTE: Must be store in 'DOS' file format convention
; logon script = logon.cmd

# This allows Unix users to be created on the domain controller via the SAMR
# RPC pipe. The example command creates a user account with a disabled Unix
# password; please adapt to your needs
; add user script = /usr/sbin/adduser --quiet --disabled-password --gecos "" %u

########## Printing ##########

# If you want to automatically load your printer list rather
# than setting them up individually then you'll need this
# load printers = yes

# lpr(ng) printing. You may wish to override the location of the
# printcap file
; printing = bsd
; printcap name = /etc/printcap

# CUPS printing. See also the cupsaddsmb(8) manpage in the
# cupsys-client package.
; printing = cups
; printcap name = cups

############ Misc ############

# Using the following line enables you to customise your configuration
# on a per machine basis. The %m gets replaced with the netbios name
# of the machine that is connecting
; include = /home/samba/etc/smb.conf.%m

# Most people will find that this option gives better performance.
# See smb.conf(5) and /usr/share/doc/samba-doc/htmldocs/Samba3-HOWTO/speed.html

# You may want to add the following on a Linux system:
# SO_RCVBUF=8192 SO_SNDBUF=8192

# The following parameter is useful only if you have the linpopup package
# installed. The samba maintainer and the linpopup maintainer are
# working to ease installation and configuration of linpopup and samba.
; message command = /bin/sh -c '/usr/bin/linpopup "%f" "%m" %s; rm %s' &

# Domain Master specifies Samba to be the Domain Master Browser. If this
# machine will be configured as a BDC (a secondary logon server), you
# must set this to 'no'; otherwise, the default behavior is recommended.
# domain master = auto

# Some defaults for winbind (make sure you're not using the ranges
# for something else.)
; idmap uid = 10000-20000
; idmap gid = 10000-20000
; template shell = /bin/bash

# The following was the default behaviour in sarge,
# but samba upstream reverted the default because it might induce
# performance issues in large organizations.
# See Debian bug #368251 for some of the consequences of *not*

; winbind enum groups = yes
; winbind enum users = yes

# Setup usershare options to enable non-root users to share folders
# with the net usershare command.

#======================= Share Definitions =======================

; browseable = no

# By default, the home directories are exported read-only. Change the
# next parameter to 'no' if you want to be able to write to them.
; read only = yes

# create files with group=rw permissions, set next parameter to 0775.

# Directory creation mask is set to 0700 for security reasons. If you want to
# create dirs. with group=rw permissions, set next parameter to 0775.
; directory mask = 0700

# By default, \\server\username shares can be connected to by anyone
# with access to the samba server. Un-comment the following parameter
# to make sure that only "username" can connect to \\server\username
# This might need tweaking when using external authentication schemes
; valid users = %S

# Un-comment the following and create the netlogon directory for Domain Logons
# (you need to configure Samba to act as a domain controller too.)
;[netlogon]
; comment = Network Logon Service

What system are you trying to transfer the files to? The problem may be at the other end.

Thank you for your interest,

I am accessing it from my mac (OSX 10.5), and other peoples' windows machines. It is slow across the board.

- The 20-50MiB/s writes -- were those from one of the same systems that is seeing the slow transfers now, or a different one?

- What method were you using to do the transfers when the speed was good (if they weren't being done over the same Samba share)?

- What sort of network are you using? Are all systems connected over gigabit Ethernet? Or is there 100 mbit Ethernet or WiFi being used for any of the systems?

FWIW I just did a quick speed test to a Samba share on my Ubuntu 8.10 box from my Windows XP box, and I appear to be getting around 25 MiB/s for both read and write.

Edit: One more Q: Are the slow transfers to the hard drive or the CF?

When I was putting things on it from my mac and getting the high speeds, I had the computers both plugged into a switch. I'm not sure why that made a difference though, because I was still using the samba sharing capabilities of the server to transfer the files. The fast transfers were on the same ubuntu system. I can get sustained 30-40MB/s if I transfer files files directly from a different server to mine, the slow speeds are taking things off mine to a personal computer. 100 mbit ethernet is being used for almost every device on the network besides the my ubuntu box. All of the transfers are between the 7200 RPM 1TB drive and external sources.

Thanks,

Nate
