Since you do that kind of testing, I can drop you VirtIO drivers for Windows 7 guest, and see how far can we go

Other news: I'm developing my own next-generation TCP/IP stack. Do you know anyone who would like to discuss this with me? (I have a presentation ready and documentation specs)

Thanks for your work,

    Hi.

    Really happy with the network performance boost with vbox5!!
    Really 900Mbps over a virtualized network is pretty good.

    One thing I notice that the outbound is slower than the inbound.
    Any suggested tweak to get the same throughput?

    The configuration:

    Vbox 5.0.20
    Virtual Machine:  Windows 2012 R2 with the 82540EM network card.

    Client:  Windows 7 on physical hardware connected via 1Gbps switch.

    Using the latest iperf tests, with default options.

    Client -> VM  903Mbps
    VM -> Client  572Mbps


Hi Alexey.

Do you see any difference between virtio and the intel card?

I can use the drivers from the redhat site: https://fedoraproject.org/wiki/Windows_Virtio_Drivers

It is going to be a bit before I actually try it out though.

At this point most of my clients are smaller and use an all-in-one server so speed isn't really a big concern; especially if we can bridge the gap between outbound and inbound connections. 900Mbps is more than fast enough for the types of servers I deploy.

thanks,

Geoff
