I can see what you are talking about. How fast this works depends on the number of products you have, the number of options and of course the resources of your server. Do you have a lot of products or product options available? I have not encountered this myself in my limited products and options that I have added to PowerStore. Please post back with these details and any other info that you have about your setup so we can get an idea of the situation behind the scenes. If I need to I will open a support ticket for you on this so we can check it out further.
