домашний файловый сервер с использованием samba низкая скорость чтения и записи

У меня есть машина под управлением ubuntu server 12.04. Я установил samba для обмена файлами в своей домашней сети. У меня есть windows и linux машина.

мои спецификации сервера: amd phenom 2 x6 1055t, 8GB ram, 10/100/1000 ethernet.

Я получаю как 6mbs/sec прочитанный и пишу.

Я просто установил linux на свой сервер, до того, как у меня был windows server 2008, и скорость была больше похожа на 50 или 60 Мбит / с.

любая идея о том, что будет причина.

спасибо

вот мой smb.конфигурации

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

[global]

## Browsing/Identification ###

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

# server string is the equivalent of the NT Description field
   server string = %h server (Samba, Ubuntu)

# 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 = w.x.y.z

# 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'.

# 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

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

   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  for
# sending the correct chat script for the passwd program in Debian Sarge).
   passwd program = /usr/bin/passwd %u
   passwd chat = *Entersnews*spassword:* %nn *Retypesnews*spassword:* %nn *passwordsupdatedssuccessfully* .

# 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

конечно, трудно диагностировать систему без подобной информации. Лучшее, что я могу сделать, это предложить эту веб-страницу вsamba.org Сайт, озаглавленный Samba performance tuning, где предлагается ряд настроек производительности.

наиболее критичным выглядит наличие опции:

 socket options = TCP_NODELAY

в разделе Опции сокета smb.файл conf ( / etc / samba / smb.conf).

другой параметр, снижающий производительность samba, - это уровень детализации операций журнала. Уровень журнала должен быть не более 2.

на веб-странице выше есть несколько других предложений, которые будут опробованы в свою очередь, я думаю, в том числе очень странная история о принтер зверское замедление передачи samba (в конце vry, в разделе производительность Samba очень медленная). Это, очевидно, поучительная история.

У меня была та же проблема. Мое решение было:

read raw = Yes
write raw = Yes
socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=131072 SO_SNDBUF=131072
min receivefile size = 16384
use sendfile = true
aio read size = 16384
aio write size = 16384

вы соединяетесь через lan или радиотелеграф ?

в любом случае, попробуйте обновить прошивку на маршрутизаторе. если не помогло, отключите firewall:

sudo ufw disable

вы можете увидеть подобную проблему здесь: http://ubuntuforums.org/showthread.php?t=2080387

расширить ответ MariusMatutiae. В дополнение к раскомментированию TCP_NODELAY (который позволяет многократную передачу пакета), вы можете включить эти опции на той же линии сокета:

IPTOS_LOWDELAY SO_SNDBUF=8192 SO_RCVBUF=8192

они имеют различные влияет на производительность, чтобы сделать с отправкой пакетов, которые могут помочь в зависимости от настройки сети. Не повредит включить их.
