virtio-win - 10Gbit network drivers?

[Martin Maurer]

Hi,

I am testing virtio net performance (10 Gbit) and its working great for Linux guests (I am using Debian Squeeze as KVM guest). 
I see just a little performance loss in the guest (compared to the host).

The win2008r2-sp1 installation, using the virtio network drivers from the Fedora projects gives just 1 Gbit performance (~ 500 to 700Mbit). Any change to improve this, do I miss anything?

My host: 
Proxmox VE 1.8 (2.6.32 Kernel, KVM 0.14.1) - if needed I can provide more details.

Best Regards,

Martin Maurer

I wish to use improved drives too, for my NICs bonded using 
round-robin.. now it's limited to 1Gbit for virtio-net.
But I think the bridge interface used to expose VMs to the LAN will 
still be limiting max speed, because CPUs have to process all this 
traffic over bridge.
