We have just released a new version of the VMware Tools which fixes the issue described in this post (below).
Please download and install this version of the VMware Tools, especially if you are using the VMXNet3 vNIC type for your Windows VMs.
We thank you very much for your patience and understanding while we worked on fixing this problem.
From the Release Notes:
Receive Side Scaling is not functional for vmxnet3 on Windows 8 and Windows 2012 Server or later. This issue is caused by an update for the vmxnet3 driver that addressed RSS features added in NDIS version 6.30 rendering the functionality unusable. It is observed in VMXNET3 driver versions from 22.214.171.124 to 126.96.36.199.
