Hi all, we just observed bad performance values with virtio network on win8r2 guests.
A simple iperf from a VM to the host shown about 700Mbit/s. Even worse, iperf between 2 win8r2 guests on the same bridge shown below 30Mbit/s. Using linux VMs, I am able to get > 9Gbit/s. I already made all optimizations suggested at: http://pve.proxmox.com/wiki/Paravirtualized_Network_Drivers_for_Windows Any ideas?
