I've tested using iperf the file server to the windows server and I've got 400Mbits. The other linux server got 600Mbits. Also I've tested iperf between windows server and another same type supermicro with hyper-v and got around 650Mbits. I've tested samba speed from windows to other linux

Hello. After reviewing the results of test, I've modified smb.conf. I've added max protocol = SMB2 and removed SO_RCVBUF=8192 SO_SNDBUF=8192 from socket options. The read speed from this server increased to 40MB/s, the write speed to this server increased to 30MB/s. On 19.12.2015 00:43, Dan

There appear to be driver issues discussed in other threads with respect to Intel driver and slow throughput due to interrupts and CPU offloading. May want to review driver parameters and look at trying a few changes. Frank On Sat, Dec 19, 2015 at 11:24 AM, Sven Hartge

Hello. I've bonded two onboard Intel 82576 Gigabit networks on an supermicro server for load balancing (round-robin). It is working, but transfer rate is about 10-20MB/s, while on same type of server the same configuration in windows I get around 100MB/s. cat /proc/net/bonding/bond0
