I have at home two centos boxes: Box A - centos 6.4. gui version Box B - centos 7.1. minimal version. They are connected to 100Mb router (both boxes have 100Mb network adapters). Box B has software raid 1 and sata II interfaces.?On box B samba4 is installed and I copy files to samba share ( from box A to box B). Network monitor (iptraf-ng) shows only 20000 kbps of this copying operation. That is around 2MB per second. CPU load on box B is around 20% on CPU1 and 1-2% on CPU2. I've checked the network speed between A (server) and B(client) via iperv: [root at localhost P]# iperf -c a.a.a.a ------------------------------------------------------------ Client connecting to a.a.a.a, TCP port 5001 TCP window size: 22.5 KByte (default) ------------------------------------------------------------ [ 3] local b.b.b.b port 53459 connected with a.a.a.a port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.0 sec 112 MBytes 94.3 Mbits/sec So I think that only samba 4 can be problem in this configuration. How to increase samba 4 fileserver perfomance? In internet people say to modify socket options but https://wiki.samba.org/index.php/Performance_Tuning says no to do it? How to solve problem of such poor perfomance?

Don't do it! Regards, Marc
Just for your reference, I have been obtaining transfer rates of 100 MB/s (Megabytes per second) and more over Gigabit Ethernet from Windows 7 clients to a Samba 4.1.17 server. So Samba 4 by itsellf is probably not your issue.
