Based on the differences between ++i and i+=1 alone I would think that there are just bugs they need to squash and that the open beta, and all these eyes on it, are going to help find the cases that are stumbling. Also, for many of the tests where it was a 400% or order of magnitude knock in performance there are a lot of comments in here refuting those results, so I'm not sure what to think yet.
