Yes, app engine does not seem very mature yet. I observed abismal performance of CPU-bound tasks (10 times slower than on my own machine with the same nominal specs). Also, when I tried to unlock the free trial, the whole admin console got locked for a few days to verify my credit card without option to undo anything. Also, I once requested a support call (from the app engine admin page), which I received within seconds, only to find out that the calling employee has never heard of "google app engine" before.
