RSS abbreviated for Receive Side Scaling, should be enabled on a VM Server as it betters performance.
Per Microsoft’s website, Virtual Receive-side scaling (RSS) is a feature in Windows Server 2012 R2 that allows the load from a virtual network adapter to be distributed across multiple virtual processors in a virtual machine.
By Default, RSS is enabled on Server 2016 and 2019 but cannot be enabled on Windows Server 2008 R2 or below.
On Server 2012 or R2 you can enable it using a simple PowerShell command.
To enable RSS run following powershell commands:
Get-NetAdapterEnable RSS by adapter name
Enable-NetAdapterRss -Name “Ethernet”Combine both commands to enable RSS on all Adapters
Get-Netadapter | Enable-NetAdapterRssTo enable from a command prompt
netsh interface tcp set global rss=enabled
This can also be enabled from the GUI. Check the Network Advanced tab and find Receive Side Scaling. Set this to Enabled if it isn’t already.
