Receive Side Scaling Windows Server 2012R2

Enable RSS Receive Side Scaling

For better performance of a virtual machine, RSS can be activated. This increases the load on a network card All virtual processors instead of just one. A vCPU brings a maximum of 7 Gbit / s, if it is now a 10 Gbit / s network, the connection cannot be used at all. For this reason you should activate RSS.

The activation of RSS under Windows Server 2012 or Windows Server 2012R2 can be implemented quickly using the Powershell:

Get-NetAdapter
Enable-NetAdapterRss -Name “Internet”
