Hyper V Network Speed Slow

Hi

I have setup a vitrual server on a hyper V host, when transfering files between a PC and the virtual server, the network transfer speed is extremely slow, there is only one switch between the PC and the Hyper V host

Is ther something wrong in the config of the virtual machine or the hyper V host network setting, ping times between Host, virtul machine and PC are all 1-2ms so this all seems fine

Server 2012 host and srver 2012 VM

Any help appreciated

1ms is a lot on LAN. It means there is at least 1000 packets buffered down the bath.
Read on on "bufferbloat" and fix your network. It wil just get worse as you use it more...

Hi
There only 3 devices the switch pc a and server with host and VM machine, how could 1ms be an issue?
Is there anything on hyper V network config that I should look at

Thanks

Set network card TX/RX buffers to minimum in all machines involved. That should reduce buffering and allow smoother TCP at cost of slightly higher CPU usage.

Are the physical NIC(s) in the server Broadcom?

If yes, then bring up the properties for the NIC(s) and disable VMQ then reboot.

That should fix the network access issues.
