[ovirt-users] Re: Max network performance on w2019 guest

Hi, Not a direct answer – but I think something to consider: -I am not sure what virtio is there ‘out of box’, but I imagine that you need to check what is latest virtio-win package containing NetKVM driver. (https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/archive-... ?) -I would imagine that main driver of higher virtio-net performance is support and use of multiqueue. I don’t know about Windows 2019 , maybe it is matter of configuration. Check out https://access.redhat.com/solutions/6638561 and https://github.com/virtio-win/kvm-guest-drivers-windows/issues/237 BR, Konstantin From: Gianluca Cecchi <gianluca.cecchi(a)gmail.com&gt; Date: Wednesday, 30 November 2022 at 10:40 To: users <users(a)ovirt.org&gt; Subject: [ovirt-users] Max network performance on w2019 guest One customer sees 2,5gbs on 10gbs adapters for w2019 VM with virtio using iperf3. Instead with Oracle linux 8 VMS of the same infra sees 9gbs. What is the expected maximum on windows with virtio based on experience? Thanks Gianluca
