HyperVisor Settings to Improve Performance

The virtual machine settings on the host Hypervisors can aid in achieving better performance.

Network Configuration -- Using VMXNET3

Configuring the virtual machines to use VMXNET3 network adapters instead of EI3000 improves the performance significantly and should be used for all the guest OS unless it causes any driver-specific issues.

Refer to the VMware KB Article for details:
