New App Engine pricing model

A while ago Google announced a new pricing for Google App Engine.
As the pricing is totally different the preview for the new billing indicated a 15x increase for Shared Groups. This would have forced us to shut down the service completely - or to increase our prices for the personal edition according to the new pricing.
After some investigation we managed to optimize the app in a way that the usage dropped significantly and we are currently expecting a price increase by ~300%.
Still quite a lot - but it looks much better than in the first place ;-)
We are constantly working on reducing the resources consumed and will come up with recommendations for all enterprise users before the new pricing will take effect.
