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 : 
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
