Network Speed from KVM streaming hd video - Help needed

[lowno]

I have been testing proxmox for a few months on a Dell Poweredge, I think t110. It has onboard gigabit ethernet, dual intel xeon. I recently upgraded from 1.6 to 1.7 with the latest KVM + KSM kernel. I mainly have been using it for asterisk and a few windows 7 KVM's.

What I am trying to do is stream a hd movie from a Windows 7 KVM to an Xbox. Essentially consolidating my last separate computer, windows 7 media center. I am successfully streaming live hd TV, and avi files, but not my 4 gig blueray rips. I believe it is due to the fact that they are larger.

I have tried many things to resolve it on my own. I have tried the e1000 and virto network drivers. I have added settings to my registry to increase buffers and TX flow. Nothing seems to work. I noticed when I was transferring 600 gigs of files from my current WMC to this one on Proxmox that the highest transfer rate I could achieve to the KVM was 9 - 10 mbps.

Are their any tips or suggestions that anyone may have to help me resolve this network issue?

I really like Proxmox and hope to consolidate this last separate computer.

Thanks

Hi,
what throughput do you reach to the host?
I do a quick test with iperf:
computer to host: 942/940 MBit/s (first Value computer as master)
computer to VM (XP, e1000, no registry changes): 739/267 MBit/s (first Value computer as master)

Hi,
i had changed the nic now to virtio - without registry changes app. the same results. With registry changes:
computer to VM (XP, virtio, registry changes): 944/864 MBit/s (first Value computer as master).
