我有一台运行 Ubuntu Server 12.04 的机器。我安装了 Samba 以便在家庭网络上共享文件。我有 Windows 和 Linux 机器。
我的服务器规格是：
- AMD Phenom 2 x6 1055t
- 8GB RAM
- 10/100/1000 以太网
我的读写速度大约为 6Mbs/秒。
在安装 Windows Server 2008 之前，我刚刚在我的服务器上安装了 Linux，速度大约是 50 或 60mbps/秒。
知道可能是什么原因造成的吗？
这是我的smb.conf配置：
#======================= 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'.
# syslog only = no
# 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 <<[email protected]> 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

# RPC pipe. The example command creates a user account with a disabled Unix
# password; please adapt to your needs

# SAMR RPC pipe.
# The following assumes a "machines" group exists on the system

# This allows Unix groups to be created on the domain controller via the SAMR
# RPC pipe.

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

# than setting them up individually then you'll need this

答案1
我也遇到了同样的问题。我的解决方案是：
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
答案2
当然，没有这样的信息，诊断系统是很困难的。我能做的最好的事情就是在桑巴网站，题为Samba 性能调优，其中建议进行一些性能调整。
如果存在以下选项，则显得最为关键：
socket options = TCP_NODELAY
在 smb.conf 文件的套接字选项部分中（/etc/samba/smb.conf）。
另一个降低 Samba 性能的选项是日志操作中的详细程度。日志级别最多应保持在 2。
上面的网页还有其他几个建议，我想可以依次尝试，包括一个关于打印机严重减慢了 Samba 传输速度（在最后，在部分Samba 性能非常慢）这显然是一个警示故事。
答案3
我只是补充一下我自己的经验，因为我也遇到过类似的问题，在搜索答案时发现了这个帖子。希望这能对某人有所帮助。
我的家庭服务器是 HP N36L，最初运行的是 Windows Home Server 2011（精简版 Windows Server 2008 R2）。由于现在不再支持，我需要更新它，但 Windows Server 选项超出了我的价格范围，因此我安装了 Linux Mint Mate 作为替代品，然后安装了 XRDP 用于远程访问，安装了 Samba 用于文件共享。
运行 Windows HS2011 时，文件传输到文件共享的速度超过 100MB/s，但使用 Linux 时只能获得 20MB/s，这令人失望。
在我升级 HP 之前，我在一台旧 PC 上进行了测试，使用 Samba 设置了 Linux，所以我回到这里并注意到到 Samba 共享的文件传输也超过了 100MB/s。
最后我终于明白了其中的区别。旧 PC 只有一个 EXT4 格式的磁盘，上面有操作系统和共享文件夹，但在我的 HP 服务器上，我保留了 2 个 NTFS 格式的数据驱动器。因此，我在 HP 服务器 EXT4 格式的驱动器上设置了一个共享文件夹作为测试，文件传输到该共享的速度超过 100MB/s。
所以我认为教训是 Samba 共享和 NTFS 格式的驱动器不是一个好的组合。
答案4
只是想让你们知道我遇到的问题，因为我一直在寻找解决方案并偶然发现了这篇文章。
我有以下内容：
Linux VM（Debian 10.9.0）位于运行 ESXi 6.0 的 HP 笔记本电脑上。该 VM 正在运行 Samba SMB 文件共享。
Windows 10（版本 1809）台式工作站。- MSI Z97-G45 Gaming、E2200 NIC 驱动程序
从 Windows 10 工作站向 Samba 共享传输文件时，速度非常慢。从 Windows 10 工作站传输到另一个 Windows 工作站时，我没有看到速度问题。
这一切都归结于 Killer Network Manager 应用程序中的设置，在设置下，确保取消勾选“启用高级流检测”，问题就会得到解决。我上传了一个视频，记录了我遇到的问题和解决方法。
