Slow wsusou install

First time using Wsusou 10.8 (after Vista sp2 re-install)and after running Update Generator the 'Client' folder showed 2.4 gb. Waiting 4hours and 'installer' still shows "listing ids of updates". Anti-virus and Windows Update Service disabled for the install of updates. Is this a normal wait time to have downloaded updates to install? How long should I wait? Should I do something else? Please advise and thanks for the help.
