Hello @30042995 - Thanks for reaching out.

Azure virtual machines (VM) have default network settings that can be further optimized for network throughput.

If your Windows VM supports Accelerated Networking, enabling that feature would be the optimal configuration for throughput.

For all other Windows VMs, using RSS can reach higher maximal throughput than a VM without RSS. RSS may be disabled by default in a Windows VM. To determine whether RSS is enabled, and enable it if it's currently disabled, please follow the below steps :
See if RSS is enabled for a network adapter with the

Get-NetAdapterRss

PowerShell command. In the following example, if you see the output like below, then RSS is not enabled.

Name : Ethernet
InterfaceDescription : Microsoft Hyper-V Network Adapter
Enabled : False

To enable RSS, enter the following command:

Get-NetAdapter | % {Enable-NetAdapterRss -Name $_.Name}

The previous command does not have an output. The command changed NIC settings, causing temporary connectivity loss for about one minute. A Reconnecting dialog box appears during the connectivity loss. Connectivity is typically restored after the third attempt.

Confirm that RSS is enabled in the VM by entering the Get-NetAdapterRss command again. If successful, the following example output is returned:

Name : Ethernet
InterfaceDescription : Microsoft Hyper-V Network Adapter
Enabled : True


For Linux VM, RSS is always enabled by default. For more details on optimizing network for Linux VM, please go through this document - virtual-network-optimize-network-bandwidth
