Check speed 50 MB/s (half connection). With nic teams speed is 2Gb/s

Answer 2

Hello there,

Have you checked the Event Viewer for any trace?

If you cannot find anything in Event Viewer I would suggest you use tools like Procmon to find the root cause for this behaviour.

Have you made any recent updates that you are aware of on this device? If so try uninstalling them and check if this sorts out the issue

Check if the copy speed in a Hyper-V VM has increased after disabling RSC. If the network speed has improved, you can disable RSC on the virtual switch the VM is connected to. You can check your network throughput using the iperf tool.

Hope this resolves your Query !!
