When I run iperf between two virtual machines, I get a bandwitch ranging from 6Gbits/sec to 10Gbits/sec. When I copy files with scp I getting a transfer speed of about 110-120MB/s which is very far from the theorical bandwitch of 1GB/s x 4 ~ 4G/s for a 40G network. Recently I discovered that encryption reduce transfer speed so, I setup FTP server. Transfer speed doubled with FTP. I got a transfer rate about 240-280 MB/s. I also updated MTU to 9000 on both hosts and VMs but transfer rates are still the same. My needs. I am looking for an Cisco/VMWare expert who can identify and solve the issue.

    In SDNs I use mininet and create different topologies such as a tree, fat tree, linear, and others, connecting them with the Ryu controller to monitor flows.

Also, change the used queue and Qos by "ovs-vsctl -- set Port s1-eth1 qos=@newqos .....". But when returning to the monitored flow I found that collision and Tx/Rx drop/error were always zero and did not change.
