Slow RDP connection to Windows Server 2012
 Thanks to the post from this link , the issue of  a very slow RDP performance on Windows Server 2012 has been solved by adding a registry entry.    Open  RegEdit  on the Windows Server machine.  Navigate to this registry key in the tree on the left:     HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters    Right-click on the right side, and add a new  DWORD (32-bit) Value  Set the value name to  DisableTaskOffload  and the value data to  1  Restart the Server  Reconnect to the Server via RDP and your performance should be normal.    I have came through many other posts suggesting disabling the "Use FIPS compliant algorithms for encryption, hashing and signing" as shown in the image below.         So far, this has solved the slow RDP connection for me.
