I suppose I could make the card list optional in the same manner as the store ticker.
I know that game speed is an issue, but to me, (and this is only me) it really doesn't matter, if it's slow at say 10p.m., then I just come back in a couple of hours and try again, for me it's usually fast real early in the a.m.. So that's when I play.
Adding the cards so they could be turned on and off is a good idea if indeed it really did speed up page loading.
