Do you have any metrics as far as improvement in your environment goes? Would you recommend this for all people, or just people with a specific problem? Hunter,

Create a new DWORD value called DisableTaskOffload, and set it to 1. Reboot. The fix: (at least in my case)

On all Xen 5.5 hosts:

xe pif-param-set uuid= other-config:ethtool-tx=”off”
xe pif-param-set uuid= other-config:ethtool-rx=”off”

Not needed, but may have been beneficial for other things:

xe pif-param-set uuid= other-config:ethtool-speed=1000
xe pif-param-set uuid= other-config:ethtool-duplex=”full”

Reboot Hosts

On all VM’s running 2003:

Start regedit
Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
Create a new DWORD value called DisableLargeSendOffload, and set it to 1.
Create a new DWORD value called DisableTaskOffload, and set it to 1.
Reboot.

Has there been any updates to the network slowness? File transfer to the server is not a problem, but from the server is a big difference.
