So...After a little testing it appears that attaching of app stacks from app volumes is the culprit. If I remove any assignments of app stacks, the Shell Load time goes down to 6 seconds. If I, add an app stack back, it bounces back up to 100+ app stack.. So far I have only tested with a few different app stacks to see if it specific to a certain app stack but seems to be happening to every app stack I have tired. Should attaching app stacks (even 1) cause the boot time to add a minute and a half at logon?
