Usually a SSD/Good RAM and CPU should open all applications including Tableau crisp and quick. I don't know if your issue is related to this. IMHO, only place HDD's can remain are in museums, not in PC's.
Unfortunately, I do not think this is related to the issue. The rest machine is running a Samsung 250GB SSD and the machine has 12GB RAM.
It is strange because upon first logon to the machine it loads incredibly quickly but every time after that initial open it is dreadfully slow. I will try installing it and using it off the network to see if there is any difference in opening speeds.
