Slow Down Host Network with Hyper-V External Network Switch

If external virtual switch is created on Virtual Switch Manager, network performance of host network is significantly decreased. Internal virtual switch is not affected.

1. Using ICS of host network

2. Using RRAS for NAT configuration

3. Disabling VMQ and/or RSC

For VMQ:> Set-VMNetworkAdapter –ManagementOS -Name -VmqWeight 0
For RSC:> Set-VMSwitch -Name vSwitchName -EnableSoftwareRsc $false

4. Using NAT via Powershell

New-VMSwitch -SwitchName “NATSwitch” -SwitchType Internal
New-NetIPAddress -IPAddress -PrefixLength 24 -InterfaceAlias “vEthernet (NATSwitch)”
New-NetNAT -Name “NATNetwork” -InternalIPInterfaceAddressPrefix
