I have installed Windows Server 2008 as a guest in a VM hosted on a VMWare ESXi 3.5 server. The performance of the user interface is very sluggish both via Remote Desktop but particularly via the Console. The mouse is very sluggish and slow to respond.. I have compared it to a fresh installation of Windows Server 2003 SP2 which works just fine. Has anyone come across this? Is there anything I can do to improve the performance?
