HyperVisor Settings to Improve Performance

Virtual machine settings on the host Hypervisors can also help in achieving better performance.

Network Configuration -- Using VMXNET3

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

Refer VMware KB Article for more details:
