Yesterday I was quite alarmed by the same issue. I have been very carefully refactoring my social web application for efficiency and yesterday my logs lit up red. I'm making heavy use of tasks & ajax and all my requests are now fine grained so as to limit their resource load. I am using all the 'tricks' I've learned about how to maximize use of the datastore so as to limit cpu cycles and speed up data store operations. There is little more I can do to lighten my application and if yesterday is any indication of the future this doesn't bode well for my application on App Engine.
I sincerely hope that the Team of Googlers, a fine bunch I might add, are addressing these issues in earnest. I'd hate to have to give up on the platform at this point as I've invested so much time & energy. Everyone who has previewed my app - i-emote - loves it and are urging me forward to a version 1 release but now I fear that I might be forced to rethink App Engine as a viable platform for my type of application. I hope you guys prove me wrong.
