I don't know if it something that I have done, or the recent Workstation update, but it is now taking forever to suspend my (quite large) guests. A Vista guest is by far the worst performer, although a fairly small Windows 8 guest is also very slow.
All my guests are split into 2GB sizes and all have recently been 'shrunk' --- (mistake?). All are running under a Windows 7 host.
Does anyone have any tips to try to improve performance short of going back to Workstation 7?
