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,... ----- Mail original ----- De: "Dietmar Maurer" <[email protected]> À: [email protected] Envoyé: Vendredi 28 Mars 2014 15:07:23 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? _______________________________________________ pve-devel mailing list [email protected] http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-devel _______________________________________________ pve-devel mailing list [email protected] http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
