Flashcards getting slower

if I have, say, 25 flashcards, I can go relatively quickly in the first row, but when I come back to the first flasch card, it suddenly becomes slower, sometimes stopping responding or jumping over some of them.
Problems with circular lists, boys?

Thanks, Ana.

We do know that there are problems with the speed of the site which affects all functionality, including the flashcards. We are working on this.
