Does anybody know, when the virtual server 2005 will support real gigabit
network speed? I mean a newer driver for the virtual-network. Is there a
roadmap to improve this weakens?

It does. Just because the card says it's connected at 100Mbps,
doesn't really mean much. The true throughput of the NIC is related
to the host machine. Generally, the NIC performs over 500Mbps on a
decent host system. The overhead is more related to it being a VM than
the emulated NIC.

Thanks, i know, that the real speed is more then 100Mbps. But our productive
virtual system has a weakness in the performance of the networkspeed. From
hardware-server to hardware-server (HP proliant DL380 G4) we got 550Mbps for
file-copying. But from the virtualserver to hardwareserver we only get
130Mbps. Although we use virtual scsci HD with fixed size an the cpu is not
really under heavy extent of utilization.
Is there a possibility to increase this poor performance with the
loopback-adapter and LAN Routing?
