samba - Nov 2014 - Tunning samba for better read performance

Hi,

I'm running samba server on board and client is windows 7.

I did below steps for performance tests.
+ format /dev/sda1 with ext4
+ mount the drive in server as mentioned in [media] path of /etc/samba/smb.conf
+ created a root password
    $ smbpasswd -a root
+ 1Gb ethernet interface from board.
+ map the driver in windows
+ did a 4gb robocopy
+ read got 13MBps and write got 105MBps

Could any one suggest me any inputs why read got too slow, do I need to look
at any config options in /etc/samba/smb.conf

thanks!

Can you post your smb.conf?

Thanks,

What mainboard is this? aka a bit more info on the hardware.
It is a nas mainboard or something like that. 

Im getting 115Mb/s read and write  from a windows 7. 
( asrock E350 AMD board ) 

1Gb interface does not mean it can reach the max speed, cpu is also important in
this,
so for that we need more hardware info.

I did a few of these : 
http://www.sysprobs.com/windows-7-network-slow 
1 is the most important. 
2 stops auto update, so dont do that.
3) possible, what you want. 
4) not really needed.
5) what you want.
6) This can be a point to check, make sure you have the latest NIC drivers. 

and no changes at samba side for me. ( only the defaults from install ) 

I get these speeds with : ( tested, and what is see in windows ) 
samba 3.6.6 ( Debian samba ) stand server		115MB/s 
samba 4.1.6 ( Ubuntu samba ) stand server 	108MB/s 
samba 4.1.13 ( Ubuntu sernet samba ) AD DC server	112MB/s

Hello Jagan,

Perhaps change the NIC driver parameters on windows 7,
Goto Control Panel -> Network and Share Center
-> Ethernet (1Gb ethernet interface on board)
-> Properties -> Configure -> Advanced,
and try followings:
1. Flow control: Disabled
2. Interrupt moderation: Disabled. Or other options.

BTW, could you post the on-board Ethernet information,
for example Intel I217-LM or Realtek Family GbE, etc,
thanks.
