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.
RSS is active by default on Windows Server 2016 and Windows Server 2019.
The activation of RSS under Windows Server 2012 or Windows Server 2012R2 can be implemented quickly using the Powershell:
Enable-NetAdapterRss -Name “Internet”
This command can be issued via the CMD. RSS is activated on all network cards.
netsh interface tcp set global rss = enabled
