I have 2 1TB samba servers on to ubuntu servers, all hooked up to a 1gb/s switch. But when i try to upload a file or copy files to them, they only copy at 2,5 megabyte/s. I have tryed to fix it ub tcant understand what's wrong. P help. https://lqo-thequestionsnetw.netdna-...s_lq/icon9.gif

Check the network speed's between the samba server and client with a tool such as iperf:

Using scp or another protocol to a transfer, to make sure it's not samba it could be network related.

http://blog.softlayer.com/2011/using...ughput-issues/


Add this to the [global] section in your /etc/samba/smb.conf

service samba restart

Now test the speeds, see if it made a difference.

I changed the smb.conf and it is the same, 6-9 mbps copying file from/to server, but only 2,5 mpbs from server to server. NOTE: it is all wired in gigabit ethernet switch... DONNO WHAT TO DO!

Give us the output of both servers:


What version of Ubuntu are you using on the servers?


What version of Samba?

#
# Sample configuration file for the Samba suite for Debian GNU/Linux.
#
#
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options most of which
# are not shown in this example
#
# Some options that are often worth tuning have been included as
# commented-out examples in this file.
# - When such options are commented with ";", the proposed setting
# differs from the default Samba behaviour
# - When commented with "#", the proposed setting is the default
# behaviour of Samba but the option is considered important
# enough to be mentioned here
#
# NOTE: Whenever you modify this file you should run the command
# "testparm" to check that you have not made any basic syntactic
# errors.
# A well-established practice is to name the original file
# "smb.conf.master" and create the "real" config file with
# testparm -s smb.conf.master >smb.conf
# This minimizes the size of the really used smb.conf file
# which, according to the Samba Team, impacts performance
# However, use this with caution if your smb.conf file contains nested
# "include" statements. See Debian bug #483187 for a case
# where using a master file is not a good idea.

this is the SMBSTATUS for the other server. Somthing wrong?

Try changing the this order:

To:

Is it different speeds from different versions of Windows ?

E.g: try copying files from a samba client using Windows XP and one from Windows 7, is there any difference in speed?

If you are having issues with Windows 7 Clients read and try this:

http://social.technet.microsoft.com/...-9587ac92d9f0/
http://www.sysprobs.com/windows-7-network-slow

The speeds are the same, only I'm getting 4mbps between the two servers, so not much faster.. Used ubuntu too, same speeds

If your transferring between the Ubuntu Servers why not use NFS or SSHFS as a share?

Samba is the standard Windows interoperability suite of programs for Linux and Unix, if your going Linux to Linux use something more native.

you beat me to it. if you are going Linux to Linux, then you are using the wrong protocol for file sharing. you should be using the native NFSv4 not SAMBA. SAMBA is for sharing between MS Windows and Linux.

i use windows, and everyone else on the lan uses it too. but I have dualboot on my pc, so just to check i booted up ubuntu, but it was not any faster.

We understand that you use Windows and that's why you have Samba share to share Linux shares between the Windows Clients.

However we are saying setup an NFS share between the Ubuntu Servers then check the transfer speeds, you can have NFS and Samba shares on the same machine.

https://help.ubuntu.com/community/SettingUpNFSHowTo

I made a nfs server. When i drag a file one server to another in windows, it transfers with 5mbps... SLOW! anyone know what to do?

First lets see if you are able to achieve faster speeds from your samba server. Take your station, or laptop, and connect it directly to the samba server via cross connect cable, and setup static IP address on it so communication can occur, and do a very large file transfer test, and also huge number of small files transferred as a group, and let us know if you get faster speeds on both transfers.

If you get fast speeds from above tests, then put the switch in between the two, and have everything else disconnected (yes, I know what I am asking can be scary in a large network environment; you could put in a backup switch temporarily) and try the tests again.

Report back.
