Hi Everyone, My doubts are for Samba4.1 performance related enhancements (SMB2.1 / SMB3.0). My experimental samba server hardware is running 4.1 version. Want to improve robocopy WRITE throughput from a two samba client machines (win7 or win8 or server2012 x86 servers). Someone please advice me how can I use SMB2.1 or SMB3.0 capabilities to improve WRITE throughput. I tried samba4.1

...ead/Write (speed MB/sec) : 210/*202* 4.1 Read/Write: (speed MB/sec) : 220/*192* In case of read am getting better throughput for samba 4.1 but write always less. How can i improve the write throughput? Am not looking to change any registry settings .( http://technet.microsoft.com/en-us/library/ff625695%28v=WS.10%29.aspx). Following tuning i already tried. http://h3x.no/2011/07/09/tuning-ubuntu-mdadm-raid56 https://erikugel.wordpress.com/tag/mdadm/ Any idea or suggestion are most welcome.Thanks in advance.

Hi, we have network performance issues with Samba (Version 4.2.7-SerNet-RedHat-19.el6) on one of our servers. The maximum throughput from client to server is 110 MB/s (read/write) under Windows 7 x64 (single 10GE NIC). When using NFS on a different Linux workstation we're getting much higher rates, around 500-700 MB/s. I still can't find the problem. Setup server: CentOS 6.6 Samba 4.7.2
