If LRO is enabled for VMXNET3 adapters on the host, activate LRO support on a network adapter on a Windows virtual machine to ensure that the guest operating system does not spend resources to aggregate incoming packets into larger buffers.
On Windows, the LRO technology is also referred to as Receive Side Coalescing (RSC).
- Verify that the virtual machine runs Windows Server 2012 and later or Windows 8 and later.
- Verify that the virtual machine compatibility is ESXi 6.0 and later.
- Verify that the version of the VMXNET3 driver installed on the guest operating system is 22.214.171.124 and later.
- Verify that LRO is enabled globally on a virtual machine that runs Windows Server 2012 and later or Windows 8 and later. See Enable LRO Globally on a Windows Virtual Machine.
- In the Network and Sharing Center of the guest operating system's Control Panel, click the name of the network adapter.
A dialog box displays the status of the adapter.
- Click Properties, and under the VMXNET3 network adapter type, click Configure.
- On the Advanced tab, set both Recv Segment Coalescing (IPv4) and Recv Segment Coalescing (IPv6) to Enabled or Disabled.
- Click OK.
