For Windows Server, when a device driver is supplied, typically through the installation of VMware Tools, the guest operating system will perceive this as a real NIC from some network card manufacturer called “VMware” and use it as an ordinary network adapter. Windows Server 2012 is supported with e1000, e1000e, and VMXNET 3 on ESXi 5.0 Update 1 or higher. VMXNET 3 driver is not supported. During the installation of Windows Server 2012 VMXNet3 is not detected by the system while creating a new virtual machine in VMware. In the hardware configuration, the network adapter type is set to use the VMXNET3 driver.

Despite all benefits, this technology has been disabled on Windows 8 and Windows 2012 Server or later due to an issue with the vmxnet3 driver which affects Windows guest operating systems with VMware Tools 9.4.15 and later. For Windows, the main issue is limited to Windows Server 2012, Windows 8 or later running on a VM with virtual hardware 11 and, of course, using vmxnet3 adapter: VMware KB 2129176 (After upgrading a virtual machine to hardware version 11 network dependent workloads experience performance degradation) describe this issue and, funny, say.

Install Vmxnet3 Driver Manually
Is anyone else running ESXi 5.5 hosts with a physical 10gig cards? We're having issues getting full (or even close to full) throughput in Windows (7,8,10,Server 2008 & 2012) VMs with the vmxnet3 adapters. Between two ubuntu VMs, even when the traffic is routed outside the vSwitch, we get around 8-9 Gb/s speeds. In Windows, we get around 3 Gb/s with some tuning in the iperf/psping tests, even less when it is routed. Adjusting some settings on the NIC in Windows yields some better results, but this shouldn't be necessary, should it?
Battlefield 2142 bots mod. We have an open medium severity case with VMware but it has been 8 (!!!) days since we have received any sort of response, and that is after a manager escalation.

The model of this particular 10GB adapter is the Intel X540-AT2, we are running the same card in all 4 of our hosts. https://heavyxxx.weebly.com/swf-decompiler-free-download.html. I have also tried updating the vmware driver for this NIC with no noticeable gain in performance.
EDIT: Just an update on this, the issue ended up being RSS not working properly, so it was not distributing the processing load among the vCPU cores. We are now getting about 8-9Gb/s with the standard 1500 MTU.
