[2Tips] Speed Up VMs Network on Windows 2012 R2/2016 Hyper-V Hosts

Fixed how to speed up Virtual Machine Network on Windows 2012 and 2016 Hyper-V Hosts. Is your VMs network very slow on windows 2016 Hyper-V hosts server or Windows 2012 server host? If yes, then this guide is for you. In the cause of physical network not supporting VMQ feature on the host, it’ll slow down to the network speed of Virtual Machine. The VMQ is a feature which is installed by default at a time of installing latest Windows 2016 Hyper-V or Windows 2012 R2 on the server. After that this feature auto enable on the physical server.

In the condition of  not supporting the VMQ by physical NIC, the VMs network will be slow down. (NIC = a kind of hardware feature). The last quote from Microsoft was “Some of NICs and manufacturers got affected in this way, but could be fixed by updating related drivers”. What to do if, it still slow Virtual Machine Network on Windows 2016 Server or windows 2012 Server? Then follow our guide how to disable VMQ feature to fix slow network performance inside Windows 2012 R2/2016 Hyper-V guest virtual machines.

There are several method available to fix slow VMs Network Performance on the internet but which one will work for you, is the question. Here, we are going to share with you that method, which was found best for us to speed up slow network performance inside Windows 2012-R2/2016 hyper-V hosts.

Speed Up VMs Network on Windows 2012 R2/2016 Hyper-V Hosts

Follow the steps below to Speed Up VMs Network on Windows 2012 R2/2016 Hyper-V Hosts. In our search we found that in case of not supporting the VMQ feature by the present server hardware (NIC), we must disable it first => Then we will go to deploying our Virtual Machine.

Step-1) First, on the server go to “NIC2 Properties” page of the physical network card => Now, click to open the Configure... As shown below.
