    Poor guest network performance

      Hi, everyone,

       

      I'm running quite a number of Windows 2003 VMs, and their network performance appears quite slow compared to physical machines on our network, even when going from VM to VM on the same host.  We're seeing throughput of approximately 500 MB/minute from VM to VM, approximately twice that (1 GB/m) from VM to physical host, and approximately four times more (2 GB/m) from physical host to physical host.  Since the VMs are not talking over the wire, I would expect them to get much closer to the theoretical maximum speed (for Windows, anyway) of the "interface."

       

      Has anyone seen this issue?

       

      Thanks,

       

      Tom
