Hi, I never reach myself more than 900Mbits with windows guest. (2003 >
2012, any virito driver
But 30mbit/s seem very slow.
Maybe trying to play with disabling offloading options (in windows guest
driver options) ? gro,gso,...

Objet: [pve-devel] win8r2 virtio net problems
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?
