Not sure if anyone else is having this issue, but with the launch of Wrath Classic and the aux update, every item I post for auction takes a long time to "scan" the AH before listing the other auctions. I am guessing it has to do with some change in the fundamental game architecture, and not the addon. Anyone else experiencing this?

It's simply the api being very slow on the mega servers. I don't think there's anything addons can do to improve it.
