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 performance significantly and should be used for all guest OSs unless it causes driver-specific issues.

Refer to the VMware KB Article for details: VMware KB Article - 1001805

For changing the existing network adapter of a VM to VMXNET3, refer to the article:
