Hi!<br />
<br />
<br />
Have an Virtual Maching that have big network performance problems, the host machine has not. &nbsp;I have tried all advanced network settings, like disable TCP Checksum Offload, that some tell you to test. Have two network adapters on the HOST-MACHINE with the same settings the second one is for the Hyper-V Machine.<br />
<br />
The lastest driver on the NIC is installed.<br />
<br />
Copy performance 500 KB/S over Gigabit LAN in booth directions. When I disabled the TCP Checksum the performance went down. I have tried all of the settings on booth VM and HOST network.<br />
<br />
Any more ideas? <br />
<br />

Microsoft server applications are those applications developed specifically, but not necessarily exclusively, on the Windows Server platform. In addition to well-known products like SQL Server, Exchange, Internet Information Services (IIS), Microsoft Dynamics, Forefront, Lync and Sharepoint, they include applications like Skype, BizTalk, Hyper-V, Groove and Commerce Server. Server applications are managed with the Microsoft System Center.

Microsoft Virtual Server was a virtualization solution that facilitated the creation of virtual machines on the Windows XP, Windows Vista and Windows Server 2003 operating systems. Virtual machines are created and managed through a web-based interface that relies on Internet Information Services (IIS) or through a Windows client application tool called VMRCplus. Features included Linux guest operating system support, Virtual Disk Precompactor, symmetric multiprocessing (SMP), x64 host operating system support, the ability to mount virtual hard drives on the host machine and additional operating systems support, including Windows Vista, and a volume shadow copy writer.
