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. The switch I used is OVSK and the links are TC link with bw=0.01MBps, delay=1s, loss=50-90%, queue size=5-100packets, and use_htp=True. 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. The traffic generates using continuous ping, Iperf3, and python server and clients script. I need a dataset like the attached image that contains non-zero values for collisions and Tx/Rx drop/error monitored by the Ryu controller. I pay for the dataset and method. I will provide the ...
