Hello friends, I have a Gigabit network with few Windows and Centos 7 machines and I noticed that when copying files via Samba from: Windows to Windows I can copy files with speed of +- 120 MBps (I think this is the max speed gigabit network can provide) But when copying files from: Centos to Centos I get only speeds of about 40 MBps Windows to Centos 40 MBps Centos to Windows 40 MBps I tried to add these lines: use sendfile = yes socket options = TCP_NODELAY IPTOS_LOWDELAY to smb.conf file but got no speed improvement, (so I think they dont need to be there, do they?) Please do you know what could be the issue? Is there some way to get full speed the network can provide? P.S.: I had the same issue on 100 mbps network - Win to Win could copy 12 MBps but Centos only 4 MBps. Thank you very much for your time Have a nice day
