First and foremost!! Thank you so much for keeping this addon alive. I took a break from the game starting in 2010 just before Mists was due to come out. I was so happy to see it still around!
I have installed the Beta because i was annoyed that the other one did not have a proper map for Timeless Isle.
i have noticed though that while working on quests and i complete a part of it, say its kill a mob, or gather an item. shortly after it lags and the game freezes for about a second. i tend to like doing raids and randoms, anyone knows that that second of hanging can be either the make or break moment of your instance.
I have removed the old carbonite and made a fresh install. It still happens.
