Hi, Virtualization layer has usually an impact on performance. If you want to lower it on vmware, be sure to use the vmxnet drivers and a good network card on the host. Ensure also you have reserved resources (both Mem an CPU) to your VM, that way no other VM can't pick up your LB capacity, decreasing its performance and decreasing your architecture performance.
